INTERFERENCE REJECTION FILTER Russian patent published in 2018 - IPC G01S13/524 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to a radar technique and is intended to isolate signals of moving targets against a background of passive interference during group rearrangement of the carrier frequency of probing pulses. Interference rejection filter contains a meter for the Doppler phase of interference, a weight unit, a complex adder, a complex multiplier, first block of the delay, the clock generator, the noise correlation coefficient meter, the weighting factor calculator, the second block of the delay, the switching unit, switching unit and a two-channel switch, interconnected in a definite way and performing coherent processing of the original samples.

EFFECT: increasing efficiency of signal extraction of moving targets against background of passive interference with priori unknown correlation properties.
