IRI"), allowing the reading of the frequency code from the ROM 160, is connected to the control inputs of the ADC 159 ₁ , ..., 159 ₁₀ , and the input of the signal "Blank" blanking meter instantaneous frequency connected to the control input limiter amplifier 155 and control inputs of differential amplifiers 158 ₁ , ..., 158 ₁₀ .

The radar signal detection system operates as follows.

At the stage of adjustment work, an operator control unit combined with a secondary processing, control and indication device 31 is used to record in the EEPROM 134 the control and exchange device 30 for the operation of digital signal processors and units based on programmable integrated circuits.

In the process of setting up a broadband multi-band receiver of the system, the values of constant detection thresholds and compensation voltages for each of the signal processing channels are determined.

In the normal mode of operation of the system, after turning on the power and completing standard test checks of computing devices, programs are downloaded from the EEPROM 134 to the DSP 132, and the configuration of the control signal generation unit 138 and the program loading control unit 135 is carried out from the DSP 132 through the serial ports SPORT0 and SPORT1 .

Then the programs are sequentially loaded into the processing units 27 ₁ , ..., 27 ₅

of signals, which is carried out by the program loading control unit 135, which receives data from the EEPROM 134 and generates control signals of the IDMA port of the DSP 132, through which the programs are loaded into the DSP 116 ₁ , 116 _{2 of the} blocks 27 ₁ , ... through the direct memory access line 17 , 27 ₅ signal processing. Download programs in blocks 115 ₁ , 115 ₂ detection and measurement of parameters is made from the DSP 116 ₁ , 116 ₂ through the serial ports SPORTO last.

After the download of programs, the direct memory access line 17 in the control and exchange device 30 is used for data exchange between the DSP 132 and the control signal generation unit 138, and in blocks 27 _i , ..., 27 _{5, the} main line 17 is used for data exchange between the unit 115 ₁ (115 ₂ ) detection and measurement of parameters and DSP 116 ₁ (116 ₂ ).

Data exchange between DSP 116 ₁ and 116 ₂ BOS 27 ₁ , ..., 27 ₅ signals and DSP 132 of the device 30 control and exchange is carried out on the highway 28 serial channel. On the same line is the interaction of the device 30 control and exchange with blocks 115 ₁ and 115 ₂ and with a digital receiving device 23.

During the operation of the system, signals from radio sources operating in the range of 26-40 GHz are received by the first ring antenna array, and from sources operating in the range of 18-26 GHz, by the second ring antenna array of the second antenna device 2.

The signals received by the CAR antenna are fed to the inputs of the antenna switches 6 _I and 6 _II , respectively, controlled by the signals “Ex. CAR _I "" Exercise CAR _II ”, by which the first to sixth inputs from the corresponding CAR antennas are sequentially switched to the switch output, or all inputs are turned off. The formation of the CAR control signals is carried out in DSP 132 of the control and exchange device 30 on the basis of a counter with the switching rate of the CAR antennas. The DSP 132 transmits the generated control codes along the direct memory access line 17 to the control signal generation unit 138, which converts them into digital signals transmitted through the buffer unit 139 to the control inputs of the antenna switches 6 _I and 6 _II .

From the outputs of the antenna switches, the received signals are fed to the inputs of the amplifier-detector blocks 7 _I and 7 _II , differing from each other only in the range of operating frequencies, where they enter the band-pass filter 44, which functions as high-pass and low-pass filters (see Fig. 3).

After bandpass filtering, the received signals are fed to a limiter-modulator 45, in which they are modulated to allow continuous signals to be received. The modulator is built on a balanced circuit with switching pin diodes. One of the arms of the modulator introduces attenuation (7 ± 2) dB and is connected to the path

the passage of the signal by the control signal supplied to the modulator from the corresponding output of the second reference voltage generator 12.

The reference voltage generator 12 generates signals in the form of a sequence of rectangular pulses with a repetition rate of 2 kHz, a duty cycle of 2 and an amplitude corresponding to the TTL levels.

The generator 12 has two coaxial outputs, designed for a load of 50 Ohms, and 16 outputs, arranged in two multi-pin connections and designed for a load of 1 kOhm. The signals at all outputs of the generator 12 reference voltages are synchronous.

The inclusion of the generator 12 reference voltages produced by the control signal "On. Mod.2 ", which is programmatically generated at the corresponding output of the control signal generation block 138 of the control and exchange device 30 in the main mode of the system and transmitted through the block 139 buffers to the control input of the generator 12.

The main amplification of the received signals through the microwave is performed in the LNA 47, which is implemented on a chip with four amplification stages. Next, through a directional coupler 48, separate channels are formed for processing pulse and continuous signals with additional amplification in the LNA 49 of continuous signals and the signals are converted to the video frequency in the detector sections 50 and 51, constructed in a serial-parallel circuit with two diodes in each branch.

The output signals of the detector sections 50, 51 are fed to the inputs of pulsed and continuous signals of the INS video amplifier unit 8 (see Fig. 4), in which the signals generated by the detector-amplifier unit 7 _I are supplied to the inputs of the _I amplifier unit 52 _{I of the} pulse signals and unit 53 _{I of} video amplifiers of continuous signals, and the signals generated by the detector-amplifier block 7 _II , to the inputs of similar blocks 52 _II and 53 _II .

The pulsed signals in blocks 52 _I , 52 _{II are} amplified by a preliminary video amplifier 55, covered by feedback on a circuit from the BALL amplifier 56 and the BAR circuit 57, which maintains a constant noise level at the output when the input noise changes, and then amplified by a logarithmic video amplifier 58, the output of which is formed pulsed video signal of the corresponding frequency range.

In blocks 53 _I , 53 _{II of} video signal amplifiers of continuous signals, in addition to pre-amplification by video amplifier 59, covered by feedback from the amplifier 60 of the BALL and the circuit 61 of the BALL, and amplification by the logarithmic amplifier 62, the signals pass through the amplifier-limiter 63, the detector 64 of the sample-storage envelope and a low pass filter 65 with a band of 400 Hz.

The amplifier-limiter 63 prevents the leakage of pulse signals exceeding the noise level to the output of the unit. The synchronous detector 64, made in the form of a sampling and storage device with a variable time constant, provides demodulation of a continuous signal modulated by the voltage from the output of the reference voltage generator 12.

The outputs of the low-pass filters 65 form the outputs of the continuous video signals of the corresponding frequency ranges of the block 8 of video amplifiers of pulsed and continuous signals of the first and second frequency ranges.

In blocks 52 _I , 52 _II , 53 _I , 53 _{II of} video amplifiers, the BALL OFF circuits are provided for external commands “Off. BALL _I "," Off BALL _II ", formed at the outputs of the block 27 ₁ signal processing. Disconnecting the BALL is made in the control mode of the receiving device.

The logarithmic video amplifier 62 of the continuous-signal video amplifier unit has a special compensation input for supplying a compensating voltage generated by the parasitic amplitude noise modulation compensation voltage adjusting unit 54, which operates as follows.

The inputs of amplifiers 66, 67 are fed positive (from 0 to 2 V) input voltage compensation U _COMP I, U _COMP II from the outputs of block 115 ₁ detection and measurement of parameters of block 27 ₁ signal processing. These voltages are amplified by amplifiers 66, 67 and transferred to a range of values from -4 V to +4 V. Next, these voltages are converted into a meander with a modulation frequency by means of keys 68, 69, controlled by reference signals from GON 12, passing to the control inputs of keys 68, 69 through the corresponding public keys of the key block 70.

The polarity and amplitude of the compensation output voltages of the PAM RNA unit 54 are set in each channel so that at the summation point on the logarithmic video amplifier 62, the compensating voltage and spurious amplitude modulation are out of phase and equal in amplitude.

The installation of compensating voltages is performed during the adjustment of the system by dialing the voltage code in the compensation submode.

Pulse and continuous video signals generated at the outputs of the unit 8 of the ANN video amplifiers of the first and second frequency ranges are received for further processing in the signal processing unit 27 ₁ , which operates as follows (see Fig. 9).

The pulse video signals BA _I , BA _II are fed to the inputs of the ADC ₁ , ADC _{2 of the} pulse signals, where they are converted into an eight-digit digital code, and then fed to the inputs of the pulse signals of the unit 115 _{1 for} detecting and measuring parameters.

Pulse signal detection is organized on the main analog comparators

AK ₁ , AK ₂ , to the first inputs of which video signals BA _I and BA _II are respectively supplied. The threshold voltage supplied to the second inputs of the comparators AK ₁ and AK ₂ is formed at the outputs of the DAC 125 with serial control from the DSP 116 ₁ , which allows you to set individual thresholds in the ranges and automatically adjust the detection threshold.

In case of simultaneous exceeding of the threshold by both BA _I , BA _II signals, the definition of the “true” reception channel is made by an additional comparator AK ₉ , which compares the signals BA _I and BA _{II with} each other.

Processing the received logical signals and making a decision about detecting a signal from a radiation source is carried out by the unit 115 _{1 for} detecting and measuring parameters, in which the amplitude, duration and period of the pulse sequence are measured.

The continuous video signals HCA _I , HCA _{II of the} first and second frequency ranges are fed to the corresponding inputs of the analog switch 124, from the output of which 119 continuous signals are alternately converted into an ADC, where they are converted into an eight-bit code, and from its output are sent to the parameter detection and measurement unit 115 ₁ in which threshold processing and detection of continuous signals are performed.

Information about the detected signals, including the time of their arrival and the values of the measured parameters, is transmitted via the direct access line 17 to the memory in the IDMA port DSP 116 ₁ , in which the programmed signal processing is performed, including:

combining signals from one radiation source into bundles with assignment of a conditional source number;

the calculation of the average parameters of the signals in the packet, in particular, the determination of the envelope envelope parameters - the maximum amplitude, temporary position and width of the main lobe of the radiation pattern;

determination of the azimuth of the radiation source by the method of discrete scanning of the CAR using information transmitted along the line 28 of the serial channel from the DSP 132 of the control and exchange device 30, in which, as mentioned above, the formation of CAR control signals is performed.

At the end of the main lobe of the radiation source radiation pattern formed in the DSP 116 _{1, the} source form containing all the measured parameters is transmitted along the serial channel 28 to the SPORT1 port of the DSP 132, control and exchange device 30 (see Fig. 10), from which through ADDR-DATA port is transmitted via the address-data bus to the controller 136 serial channels, and then through the block 137 transceivers on the serial line

channel is transmitted to the device 31 of the secondary processing, control and indication.

The system provides the ability to manually adjust the gain of the received signals, which in the first and second frequency ranges is performed using attenuators 46 of the amplifier-detector units 7 _I , 7 _II , made on the basis of a preliminary microwave amplifier, the gain of which decreases by 25 dB when a control signal is applied “On Att. I ”(“ Inc. Att. II ”).

Signals “On Att. ”Are formed by pressing the appropriate buttons on the front panel 151 by the operator (see FIG. 11), and then through the button signal generation unit 150 enter the processor module 142, from which through the controller 145 serial channels and the interface conversion unit 152 along one of the lines groups of 29 serial channels enter the block 137 transceivers of serial channels of the control and exchange device 30 (See FIG. 10).

In the control and exchange device 30, the attenuation enable signals via the serial channel controller 136 are transmitted via the address-data bus to the digital signal processor 132, and from it through the serial port SPORT1 to the serial channel 28, through which the parameters are detected and measured block 115 ₁ through his input program downloads. Next, the inclusion signals of the attenuators from the corresponding outputs of block 115 ₁ through a buffer 128 of discrete signals are transmitted to the control inputs of the attenuators 46 of the amplifier-detector blocks 7 _I and 7 _II .

Because when you turn on the attenuators 46, introducing attenuation from 20 to 30 dB, parasitic amplitude modulation of noise is absent, simultaneously with the formation of signals “On. Att. I ”,“ On. Att.II "at the outputs of the unit 115 ₁ detection and measurement of the parameters are formed off signals compensation" Off. Comp. I ”,“ Off Comp. II ”, which enter the control inputs of the corresponding keys of the block of keys 70 in the block 54 of the RAM PAM and close them.

If it is necessary to disconnect the LNA 47 and 49 during routine inspection and control of the receiving device, they are turned off by the signals “Off. LNA ", formed at the output of block 138 of the formation of control signals of the device 30 control and exchange.

The reception of signals from radio sources operating in the third (8-18 GHz), fourth (2-8 GHz) and fifth (0.2-2 GHz) frequency bands is carried out simultaneously by the broadband mirror antenna of the first antenna device 1 and three CARs of the third antenna devices 3.

The signals received by the first antenna device 1, enter the frequency separation and amplification device 9, constructed according to a three-channel circuit with

frequency separation module 71 at the input, forming three frequency channels with adjacent frequency bands (see figure 5).

The signals of each frequency range pass respectively through the limiters 72 _III , 72 _IV , 72 _V , are modulated for the possible reception of continuous signals by modulators 73 _III , 73 _IV , 73 _V and amplified by the LNA 76 _III , 76 _IV , 76 _V microwave. The signals of the fifth frequency range after the main gain are additionally amplified by the LNA 77.

Modulation signals arriving at the control inputs of modulators 73 _III , 73 _IV , 73 _V are generated by the first generator 11 of the reference voltage.

The frequency separation and amplification device 9 provides the possibility of two-stage gain control by means of attenuators 74 _III , 74 _IV , 74 _{V of the} first stage of gain control, which are turned on simultaneously by the control signal “On. Att. 1 ”and attenuators 75 _III , 75 _IV , 75 _{V of the} second stage of gain control, which are turned on separately when the control signals“ On. Att. III ”,“ On. ATT.IV ”and“ On. Att.V ".

Disabling LNA 76 _III , 76 _IV , 76 _V during routine monitoring of the frequency separation and amplification device 9 is carried out with the signals “Off. LNA _III "," Off. LNA _IV ”and“ Off LNA _V "generated at the respective outputs of the control signal generation unit 138 of the control and exchange device 30.

The output signals of the CAR antennas of the third antenna device 3 are respectively supplied to the inputs of the switching and amplifying devices 15 _III , 15 _IV , and 15 _{V of the} third, fourth and fifth frequency ranges (see Fig. 7), which form the inputs of the antenna switch 96.

Antenna switch 96 is built according to the beam pattern on pin diodes with series-parallel connection of diodes. To protect the switches from high power signals, a limiter built in a passive circuit on detector pin diodes is built into each of the six input channels of the 6: 1 switch. The limiter withstands microwave power up to 3 watts in continuous mode and up to 10 watts in pulsed mode.

One at a time switching the output of the antenna switch 96 of the input signals of the respective antennas CAR produced control signals to the decoder 102 outputs, in which the input unit 15 receives signals _III 'mgmt. CAR _III ", and in devices 15 _IV , 15 _V - signals" Exerc. KAP _IV "and" Ex. KAP _V "generated at the respective outputs of the control signal generation unit 138 of the control and exchange device 30.

The signals from the output of the antenna switch 96 pass through a band-pass filter 97 (with a bandwidth corresponding to the channel lettering), and a limiter

98 into a modulator 99, built in a U-shaped circuit with an attenuator (7 ± 2) dB included in one of the arms, and with switching elements in the arms made on pin diodes. After modulation, the signals are amplified in the LNA 101, implemented on field-effect transistors with a total gain of 45 to 50 dB. The gain control of the LNA 101 is carried out by means of an attenuator 100 constructed in a two-stage scheme. Each of the stages operating synchronously introduces a 15dB attenuation. The attenuation of 100 switching amplification devices 15 _III , 15 _IV , 15 _V is turned on by the control signals “On. Att. III ”,“ On. Att. IV ”and“ On. Att.V ”, respectively.

Disabling the LNA 101 during routine monitoring of switching and amplification devices of the third, fourth and fifth frequency ranges is carried out with the signals “Off. LNA _III "," Off. LNA _IV ”and“ Off LNA _V "generated at the respective outputs of the control signal generation unit 138 of the control and exchange device 30.

The modulation signals supplied to the control inputs of the modulators 99 of the switching and amplifying devices 15 _III , 15 _{IV of the} third and fourth ranges are generated by the third reference voltage generator 13, which is turned on simultaneously with the first reference voltage generator 11 by the control signal “On. Mod. 1 ”, which is formed at the corresponding output of the control signal generation unit 138 of the control and exchange device 30.

The modulation signals supplied to the control inputs of the modulator 99 of the switching amplifier 15 _{V of the} fifth frequency range are generated by the fourth reference voltage generator 14, the inclusion of which is carried out by the control signal “On. Mod.3 ".

Microwave signals of the third and fourth frequency ranges from the outputs of the frequency separation and amplifying device 9 are fed to the first two-channel receiving device 10 of the signals of the third and fourth frequency ranges, and the microwave signals from the outputs of the switching and amplifying devices 15 _III , 15 _IV are fed to the inputs of the second two-channel receiving device 16 signals of the third and fourth frequency ranges, made similar to the receiving device 10 (see Fig.6).

In each of the receiving devices 10, 16, the signals of the third and fourth frequency ranges are supplied to blocks 78 _III and 78 _{IV of} amplifiers and power dividers, respectively, in which preliminary amplification is performed, separation of a part of the power of microwave signals by means of directional couplers 84 ₁ and 84 ₂ for subsequent measuring the instantaneous frequency and dividing the power by means of power dividers 86 _III and 86 _IV into two outputs connected to the inputs of the corresponding bandpass filters of blocks _{III III} and 79 _{IV of the} bandpass filtering and conversion e-frequency.

In block 79 _III, through the bandpass filters 87 ₁ and 88 ₁ , the signals of the upper (B) frequency band and the lower (H) frequency band are extracted, and the narrowband (UP) signal of the third frequency range is selected by the bandpass filter 91 ₁ . Further, the generated signals are separated by directional couplers 92 ₁ , 92 ₂ , 92 ₃ each into two outputs for subsequent separate processing of pulsed and continuous signals and converted to a video frequency. In this case, the signals of the pulsed channels directly go to the video detectors 93 ₁ , 93 ₂ , 93 ₃ , and the signals of the continuous channels go to the video detectors 94 ₁ , 94 ₂ , 94 ₃ after additional amplification of the LNA 95 ₁ , 95 ₂ and 95 ₃ .

Further, the generated pulsed and continuous video signals are fed to the inputs of the pulsed and continuous signals of blocks 81 _III-B , 81 _III-UP and 81 _III-H , the outputs of which are formed respectively pulsed and continuous video signals of the upper frequency band (12-18 GHz), narrow-band pulsed and continuous video signals and pulsed and continuous video signals of the lower frequency band (8-12 GHz) of the third frequency range.

In block 79 _IV, using the bandpass filters 87 ₂ and 88 ₂ , the signals of the upper (B) frequency band and the lower (H) frequency band are extracted, and the narrow-band (UP) signal of the third frequency range is selected by the bandpass filter 91 ₂ .

Further, a conversion to a video frequency similarly occurs with the formation of separate amplification channels for pulsed and continuous video signals, which is performed in blocks 81 _IV-B , 81 _IV-UP and 81 _IV-H , at the outputs of which pulsed and continuous video signals of the upper frequency band are formed (4- 8 GHz), narrow-band pulsed and continuous video signals and pulsed and continuous video signals of the lower frequency band (2-4 GHz) of the fourth frequency range.

Compensation voltages for the continuous signal processing channels of blocks 81 _III-B , 81 _III-UP and 81 _III-H , and 81 _IV-B , 81 _IV-UP and 81 _IV-H are generated by the PAM unit 80 RNA, operating similarly to the 54 RNA unit LAM.

The reference voltages for the PAM RNA block 80 of the receiving device 10 are formed by the first reference voltage generator 11, and for the PAM RNA block 80 of the second receiving device 16 are formed by the third reference voltage generator 13.

Pulse and continuous video signals of the third frequency range generated at the outputs of the receiving units 81 _III-B , 81 _III-UP and 81 _{III-H of the} first and second receiving devices 10, 16, enter the block 27 ₂ signal processing, pulsed and continuous video signals of the upper band frequencies of the fourth frequency range and narrow-band pulsed and continuous video signals of the fourth frequency range,

generated at the outputs of blocks 81 _IV-B and 81 _{IV-UP of the} receiving devices 10 and 16, enter the block 27 ₃ signal processing, and pulsed and continuous video signals of the lower frequency band of the fourth frequency range, formed by the outputs of the blocks 81 _{IV-H of the} receiving devices 10 and 16, are fed to the inputs of the signal processing unit 27 ₄ .

Accordingly, the compensation voltages for the channels for processing continuous signals of the third frequency range, supplied to the corresponding inputs of the RNA blocks 80 of the first and second receiving devices 10 and 16, are generated at the outputs of the blocks 115 ₁ , 115 _{2 for} detecting and measuring the parameters of the biofeedback 27 ₂ , the compensation voltage for the channels processing of continuous signals of the upper frequency band and narrow-band pulse and continuous signals of the fourth frequency range are generated at the outputs of blocks 115 ₁ , 115 ₂ BOS 27 ₃ , and the compensation voltage for The processing of pulsed and continuous signals of the lower frequency band of the fourth frequency range is at the outputs of blocks 115 ₁ and 115 ₂ BOS 27 ₄ .

The SHARU shutdown signals of the 81 video amplifiers of pulsed and continuous signals during routine inspection of the receiving devices 10, 16 are generated at the outputs of the corresponding biofeedback devices 27 ₂ , 27 ₃ , 27 ₄ , as shown in FIG. 2.

Signal processing in blocks 27 ₂ , 27 ₃ , 27 ₄ occurs similarly to signal processing in block 27 ₁ , discussed above. The difference lies in the fact that due to the large number of input signals, their processing is performed synchronously by both units 115 ₁ , 115 _{2 for} detecting and measuring parameters and by both DSPs 116 ₁ , 116 ₂ .

In addition, the corresponding external synchronization signals arriving through the buffers 129, provides synchronous processing of information in all three blocks 27 ₂ , 27 ₃ , 27 ₄ signal processing.

The main threshold processing of pulsed video signals is performed using comparators AK ₁ , ..., AK ₆ , and the determination of the “true” reception channel in case of exceeding the threshold by several input pulsed video signals is performed by comparing adjacent signals using comparators AK ₉ , ... AK ₁₄ .

Processing the received logical signals and making a decision about the detection is performed in blocks 115 ₁ and 115 ₂ .

In this case, the detection signals “Obn. IRI ”, arriving through buffer 127 from block 27 ₂ to the meter 36 of instantaneous frequency, from block 27 ₃ to the IMCI 37, and from block 27 ₄ to the MPI 38. Accordingly, the signals generated by the MPI 36, 37, 38 go to the blocks 27 ₂ , 27 ₃ , 27 ₄ signal processing.

IMCh 36 measures the carrier frequency of the microwave signals of the third frequency range, arriving at its input from the second outputs of the directional couplers 84 _{1 of the} receiving devices 10 or 16 through a switch 33 channels. Switching

channels produced by applying to the control input of the switch 33 signal "Ex. PK ₁ ", which is formed at the output of the unit 115 for detecting and measuring parameters, and transmitted through a buffer 128 of discrete signals BOS 27 ₂ .

The measurement of the carrier frequency of the signals of the fourth frequency range from the second outputs of the directional couplers 84z of the receiving devices 10 and 16 to the inputs of the second channel switch 34 is carried out by two IFIs 37 and 38. The signal from the output of the switch 34 is fed first to the power divider 32, from one arm of the divider 32 power, a part of the power is supplied to the IFI 37, providing measurement of the carrier frequency in the range of 4-8 GHz, and on the other, to the IFI 38, providing measurements in the range of 2-4 GHz.

Control signal PC ₂ ", on which the channel switching is performed, is formed at the output of the unit 115 for detecting and measuring the parameters of the biofeedback 27 ₃ .

The meters 36, 37, 38, as well as the meter 39 instantaneous frequency, providing measurements of the carrier frequency in the range of 0.2-2 GHz, operate as follows (see Fig.12).

The microwave signal supplied to the input of the instantaneous frequency meter passes through a band-pass filter 154, amplifier-limiter 155, which provides signal amplification by at least 55 dB, and is fed to the input of a multi-channel power divider 156, which divides the signal power into several measurement steps.

The main measuring elements of the PMI are frequency discriminators 157 ₁ , ..., 157 ₅ . Each frequency discriminator contains a power divider into two channels, one of which is a reference, and the other contains a delay line with a known delay time. In addition, each frequency discriminator comprises a broadband phase shifting device and phase detectors based on directional couplers whose arms are loaded with quadratic detectors.

The phase detector allows you to measure the phase difference between the reference channel and the channel with the delay line. Based on the measured value of the phase difference, the frequency value of the input microwave signal is calculated.

The delay lines provide a constant delay time of the signal regardless of its frequency, i.e. are non-dispersive.

To ensure the accuracy and uniqueness of frequency measurement over a wide range of frequencies, a set of frequency discriminators with multiple delay lines is used.

Discriminators with short delay lines provide unambiguous measurements, and with long ones - resolution and frequency measurement accuracy.

The quadrature signals generated at the outputs of each frequency discriminator 157 ₁ (157 ₂ , ..., 157 ₅ ) are amplified by the corresponding differential amplifiers 158 ₁ , ..., 158 ₁₀ (each with a frequency band of 10 MHz and a gain of 1000) and are converted in the ADC 159 ₁ , ..., 159 ₁₀ into a non-positional code of the frequency (phase) of the signal, the least significant bits of which are used to eliminate the ambiguity of measuring the frequency (phase) in frequency discriminators with delay lines of shorter length. The outputs of the ADC 159 ₁ , ..., 159 _{10 are} connected to the ROM 160.

In ROM 160, non-positional codes of each frequency discriminator are converted for 30 not into a twelve-digit binary frequency code "Code f", while the readiness signal of the IMC "Goth. IMH ".

The reading of the code of the carrier frequency is made, in the presence of a detection signal "Obn. IRI ”, formed by the unit 115 for detecting and measuring the parameters of the corresponding biofeedback, and arriving at the MPI at the control inputs of the ADC 159 ₁ , ..., 159 ₁₀ .

The phase shift keying device 161 recognizes phase-shift keyed signals by counting the number of phase transitions (0 °, 180 °) and, after ten transitions (10π-keyings), produces a FM detection signal “Obn. FM ". After that, the device 161 generates a signal "Video FM" in the form of a sequence of pulses coinciding in time with the moments of phase transitions of the input signal.

The above output signals of the UHF are transmitted to the unit 115 for detecting and measuring the parameters of the corresponding BOC 27 through the buffer 127 of the interface of the UHF. To ensure the operation of the long-pulse PMI, blanking of the amplifier-limiter 155 and differential amplifiers 158 ₁ , ..., 158 by ₁₀ pulses “Blank” with a duration of 1 to 2 μs, formed every 10 μs, is provided. This eliminates the phenomenon of a decline in the peak of the pulse, which can lead to a dependence of the measured value of the instantaneous frequency on the pulse signal at the output of the differential amplifier. Signals "Blank" are formed at the output of block 115 for detecting and measuring the parameters of the corresponding biofeedback.

Thus, in the signal processing blocks 27 ₂ , 27 ₃ , 27 ₄ that process the signals of the third and fourth ranges, additional information is received from the instantaneous frequency meters, which allows to supplement the list of measured signal parameters with the values of the lower and upper carrier frequencies of the signals received from the IRI, as well as the number of phase transitions of the FM signals.

In addition, when processing the signals of the third and fourth frequency ranges, the azimuth of the detected source of radio emission is determined

by two methods: by the method of discrete scanning of the CAR and by the radiation pattern of the mirror antenna of the first antenna device 1. In this case, the signal of the angular position of the antenna "Code ψ _A " enters the block 137 transceivers of serial channels of the control and exchange device 30 and is transmitted through the controller 136 serial channels via the address-data highway to the ADDR-DATA port of the DSP 132, from which through the serial port SPORT1 it enters the program download input of the unit 115 for detecting and measuring the parameters of the corresponding biofeedback (27 ₂ , 27 ₃ or 27 ₄ ).

The rest of the work of BFL 27 ₂ , 27 ₃ , 27 _{4 is} similar to the work of BFB 27 ₁ .

The microwave signal from one of the arms of the power divider 41 is directly fed to the input of the pulse signals of the second block 43 of the ANN detector-video amplifiers of the fifth frequency range, and the signals received at its input of continuous signals from the second arm of the power divider 41 are further amplified by the microwave amplifier 42.

The operation of the block of detectors-video amplifiers 43 ANN, consisting of the input detector section and the block of video amplifiers of pulsed and continuous signals with a PAM RAM board, is similar to the above operation of block 8 of video amplifiers ANN.

The reference voltage for the PAM unit RNA unit 43 is generated by the first reference voltage generator 11.

The input signal is supplied to a band-pass filter 103 having a passband from 0.136 to 0.174 GHz and then fed to the input of the limiter-modulator 104, which protects the subsequent stages of the amplifiers from the effects of powerful radio signals from the air and to implement the modulation of the received radio signals, which allows to realize the reception of continuous signals as pulse.

The modulation control signals supplied to the limiter-modulator 104 are generated by the fourth reference voltage generator 14.

After amplification of the LNA 105, filtering by a band-pass filter 106, which differs from the band-pass filter 103 by the presence of an internal decoupling attenuator of 3 dB, and amplification of the LNA 107, the signal branches out using a band-pass filter 108 having an output power divider.

Part of the power from the output of the bandpass filter 108 is supplied to a digital receiver 23, which directly determines the parameters of the received signal, including the carrier frequency, by spectral analysis methods (fast Fourier transform algorithm). The data generated at the output of the digital receiving device 23 is transmitted via the serial channel 28 to the control and exchange device 30, and from there to the secondary processing device 31.

Another part of the power is used for analog detection, namely: amplified by LNA 109, partially absorbed by a selectable attenuator 110 to provide the necessary dynamic range of the entire receiving path, and branches out using a band-pass filter 111 with an output power divider into two arms, the first of which is directly connected to the input of the pulse signals of the block 114 of the ANN detector-video amplifiers, and the second is connected to its input of continuous signals through the LNA 112 and a fixed attenuator 113 (6 dB).

In block 114 of the detector-video amplifier, including the PAM RNA unit, separate amplification of pulsed and continuous signals with PAM compensation is carried out.

Processing of pulsed and continuous video signals of the fifth frequency range and narrow-band pulsed and continuous video signals of the sixth range is carried out in BOS 27 ₅ , and is similar to signal processing in BOS 27 ₂ , 27 ₃ , 27 ₄ .

The gain control of the receiving paths of the fifth frequency range is carried out by the signals “On. Att.V ”, which are generated by the operator and transmitted to the control inputs of the attenuator 100 of the switching and amplifying device 15 _V and to the control input of the attenuator 75 _{V of the} frequency separation and amplifying device 9 similarly to those discussed above.

Disabling the BALL block 114 of the detector-video amplifier during routine inspection of the receiving device 22 is made by the control signals "Off. BALL _VI ", which is formed on the corresponding output of the biofeedback 27 ₅ .

In addition, the structure of the device 31 secondary processing provides the ability to communicate with external systems through the switch 147 of the local area network Et hernet connected to processor module 142.

The simultaneous use of two different antenna devices for receiving signals of the third, fourth and fifth frequency ranges increases the information content of the system and, when the signals are processed simultaneously by the same processing units, allows to expand the arsenal of software for more accurate determination of the parameters of detected IRI.

The use of additional threshold processing by comparing signals of adjacent frequency ranges increases the reliability of determining the true receive channel.
