FILTER COMPENSATION OF PASSIVE INTERFERENCE 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. Passive interference compensation 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, switching unit, switching unit and two-channel switch, which are interconnected in a certain way and performing coherent processing of the original samples.

EFFECT: improving the efficiency of the extraction of signals from moving targets against the background of passive interference with a priori unknown correlation properties.
