Description

  The present invention relates to a secondary radar apparatus, an observation method, and a program.

  In a system using an SSR device, which is a secondary radar (SSR) device used for air traffic control, communication is performed between an SSR device installed on the ground and an aircraft. Using this communication, the SSR device performs aircraft target detection and simultaneously obtains aircraft identification information for identifying the aircraft. In this SSR communication method, three types of information, that is, a mode A code, a mode S address, and an aircraft ID (hereinafter referred to as “ACID”) are used as aircraft identification information detected as a target.

In addition, as an SSR communication system, there are an ATCRBS (Air Traffic Control Radar Beacon System) system and a mode S system, and the ATCRBS system has been operated in the conventional system.
However, due to the development of air traffic control technology and the increase in air traffic flow, the ATCRBS method has limited control operation, and a new communication mode, Mode S method (Mode S protocol), has been standardized and provided for air traffic control operation. It has come to be.

  These ATCRBS and Mode S protocols are established when the aircraft responds to the interrogation radio waves from the SSR device with radio waves having a frequency of 1090 MHz. In recent years, ADS-B (Automatic Dependent Surveillance-Broadcast), which broadcasts location information and aircraft identification information, has been widely used by aircraft spontaneously transmitting radio waves with a frequency of 1090 MHz, and can also be used for air traffic control operations. The situation is under consideration.

  Also, a technique for determining the reliability of the ADS-B signal by comparing the first position, which is the position of the aircraft included in the ADS-B signal, with the second position, which is the position of the aircraft, is considered. (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 2008-130047

In order to acquire the mode S address and the ACID from the aircraft among the above-described information, it is necessary to perform an operation using a dedicated communication protocol called mode S operation in the SSR. In mode S operation, a unique number called II code indicating the SSR of the communication source is required in the communication protocol. Since the number of assigned II codes is limited, when a plurality of SSRs are operated at the same time, II codes cannot be assigned to some SSRs, and only the mode A code called ATCRBS operation is used for the SSRs. It will be limited to the operation to get.
As a result, the aircraft identification information obtained from the SSR operated by ATCRBS cannot satisfy what the air traffic control system expects, and there is a problem that the air traffic control operation is limited.

On the other hand, as a target detection method that does not use the secondary radar, there is ADS-B in which the aircraft transmits position information, but the main identification information output by ADS-B is the mode S address and ACID, and the mode A code The number of aircraft that output is small.
For this reason, even with ADS-B alone, aircraft identification information expected by the air traffic control system cannot be obtained, and there is a problem that air traffic control operation is limited in the same manner as ATCRBS operation.
Further, the technique described in Patent Document 1 only inspects the ADS-B signal and has the same problem.

  As described above, the above-described technique has a problem that the air traffic control operation is limited.

  The objective of this invention is providing the secondary radar apparatus, the observation method, and program which solve the said subject.

The integration unit 131 integrates and outputs the information acquired by the first acquisition unit 111 and the information acquired by the second acquisition unit 121. Specifically, the integration unit 131 compares the target detection information acquired by the first acquisition unit 111 with the target position information acquired by the second acquisition unit 121, or is acquired by the first acquisition unit 111. The mode A code information and the mode A code information acquired by the second acquisition unit 121 are collated, and based on the result of the collation, the input information acquired by the first acquisition unit 111 and the second information Are integrated with the input information acquired by the acquisition unit 121. The integration unit 131 outputs the integrated information to the air traffic control system 401. The integrated information is target detection information or target position information, mode A code information, mode S address, and target identification information.

  Below, the observation method in the secondary radar apparatus 101 shown in FIG. 3 is demonstrated. FIG. 5 is a flowchart for explaining an observation method in secondary radar apparatus 101 shown in FIG.

First, the first acquisition unit 111 acquires target detection information of the aircraft 301 and code information of mode A (step S11). In addition, the second acquisition unit 121 receives the mode S address of the aircraft 301 received by the ADS-B receiver 201 connected to the outside, target identification information for identifying the aircraft 301, Target position information indicating the position and, if possible, mode A mode code information are acquired (step S12).
Then, the integration unit 131 collates the target detection information acquired by the first acquisition unit 111 with the target position information acquired by the second acquisition unit 121, or mode A acquired by the first acquisition unit 111. And the mode A code information acquired by the second acquisition unit 121 are checked to determine whether or not they match each other (step S13).
When the integration unit 131 determines that the target position information included in the target detection information acquired by the first acquisition unit 111 and the target position information acquired by the second acquisition unit 121 match, The information acquired by the first acquisition unit 111 and the second acquisition unit 121 is integrated (step S14). Alternatively, when the integration unit 131 determines that the mode A code information acquired by the first acquisition unit 111 and the mode A code information acquired by the second acquisition unit 121 match, The information acquired by the first acquisition unit 111 and the second acquisition unit 121 is integrated.

As described above, the secondary radar apparatus 101 obtains the mode S address of the aircraft 301 received by the ADS-B receiver 201 provided outside the aircraft 301, in addition to acquiring the mode A code information of the aircraft 301, and the aircraft Target identification information for identifying 301, target position information indicating the position of the aircraft 301, and mode A code information are acquired and integrated. Therefore, in the SSR operated by ATCRBS, the aircraft identification information of the radar target data is made the same as that of the SSR operated by mode S by acquiring the mode S address and ACID from the ADS-B receiver 201 provided therewith. Is possible. As a result, the aircraft identification information required in the air traffic control operation can be obtained from the SSR limited to the ATCRBS operation, and the air traffic control operation without limitation can be realized.
(Other embodiments)

Other embodiments will be described below.
The frequency of the radio wave used by the SSR is 1090 MHz, and the ADS-B receiver uses the same 1090 MHz radio wave. Therefore, the ADS-B antenna part can be reduced by sharing the antenna part for receiving radio waves between the SSR and the ADS-B receiver.

  Here, even if the SSR performing the ATCRBS operation is premised on having the function of processing the mode S protocol, the mode S protocol and the ADS-B signal use the same method. Therefore, the SSR signal processing unit can be shared by the SSR and the ADS-B receiver. The ADS-B signal processing unit can be reduced by processing the ADS-B signal acquired by the ADS-B antenna unit by the SSR signal processing unit.

  Further, the ADS-B antenna unit and the ADS-B signal processing unit can share the SSR antenna unit and the SSR signal processing unit, respectively. By sharing the antenna unit and the signal processing unit with the SSR signal processing unit, the ADS-B receiver can be physically reduced.

  As described above, each function (process) is assigned to each component, but this assignment is not limited to the above. In addition, the configuration described above is merely an example, and the present invention is not limited to this.
