FIELD: radio engineering.
SUBSTANCE: invention relates to radar technique and can be used to isolate signals of moving targets against background of passive interference during group rearrangement of carrier frequency of probing pulses. Result is achieved by the fact that interference rejection filter comprises doppler phase meter of interference, block combiner, complex combiner, complex multiplier, first delay unit, sync generator, interference correlation meter, weight calculator, second delay unit, switching unit, switching unit and two-channel switch, interconnected so as to coherently process original samples.
EFFECT: increasing efficiency of signal extraction of moving targets against background of passive interference with priori unknown correlation properties.
