METHOD OF INTERFERENCE COMPENSATION AND COMPLEX FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01S7/36 

FIELD: radar ranging and radio navigation.

SUBSTANCE: inventions relate to the field of radar ranging and can be used in radar stations for protection from pulse, including response, interference. Technical result is achieved by the fact that in method of compensation for radar station interference based on reception of signals by main and additional channels, on adjustment of automatic equalizer parameters, providing for subtraction of signals received from direction of interference source, signals reception by additional channel is performed through retransmitter, re-reflecting incident signals of interference producer interference, interference signals received by the main channel are delayed until a signal appears in the additional channel and compensated for at the output of the automatic equalizer. Technical result is achieved by a complex comprising a radar station for pulse interference (PI) compensation and an PI relay, wherein the radar station for the PI compensation system comprises a main antenna, an additional directional antenna, a main receiving-transmitting and additional receiving channels, an automatic equalizer, a synchronizer, an input/output of the main antenna is connected to the input of the main channel, output of additional antenna is connected to input of additional channel, automatic equalizer is made in digital form, repeater, threshold device (TD), two analogue-to-digital converters (ADC), random access memory (RAM), gating device, main channel output is connected to input of first ADC output of which is connected to first input of RAM, additional channel output is connected to input of TD, first output of TD is connected to input of gating device and second input of RAM, second output of TD is connected to input of second ADC, output of second ADC is connected to second input of digital automatic equalizer, first input of digital automatic equalizer is connected to output of RAM, output of gating device is connected to fourth input of digital automatic equalizer, first output of synchronizer is connected to third input of digital automatic equalizer, and second to third input of RAM.

EFFECT: compensation of PI at maintaining conditions of reception of signals reflected from the target.
