Now, controller 110 adjusts control signal, to change the frequency band for the detectable signal that emitter 120 is launched or modulation system.
Then, radar installations repeat the Interference Detection course of work, change control signal, until echo-signal in do not interfere with signal or
During interference signal very little, the radar installations is just operated in next cycle using the frequency band after adjustment or modulation system.
The embodiment of the present invention adds Interference Detection working condition by increasing controllable attenuator in radar installations,
Radar installations detects the radar installations that can be interfered with the presence or absence of other in the same area when being in the state, if work be present
In same frequency band or the radar installations of modulation system, then change the frequency band or modulation methods of this radar installations emission detection signal
Formula, the problem of multi-section radar installations interferes in the region can be so avoided, strengthen the adaptive capacity to environment of radar installations
With detecting target capability.
Alternatively, radar installations provided in an embodiment of the present invention also includes signal conditioning circuit 170, the signal conditioning circuit
170 signal input part is connected with the signal output part of frequency mixer 160, the signal output part of signal conditioning circuit 170 and 110 controls
The signal input part connection of device processed;
The base band echo-signal that signal conditioning circuit 170 is used for self-mixing device in future 160 carries out being processed and transmitted to control
Device 110.
Alternatively, the signal conditioning circuit 170 is amplified to base band echo-signal, and adjusts the base band echo-signal
Bandwidth.
The embodiment of the present invention can be filtered by the signal conditioning circuit to base band echo-signal, only allow by with
The base band echo-signal of set frequency band, it can so improve the speed that controller 110 handles base band echo-signal;And may be used also
To improve the detection performance of radar installations.
