INTERFERENCE COMPENSATION FILTER Russian patent published in 2018 - IPC H04B1/10 

FIELD: navigation system.

SUBSTANCE: invention relates to a radar technique and can be used to isolate signals of moving targets against a background of passive interference during group rearrangement of the carrier frequency of probing pulses. Said result is achieved by the interference compensation filter comprises first, second and third delay units, a weighting unit, first and second complex multipliers, weight block, complex adder, clock generator, a complex conjugation unit, a switching unit, an accuracy unit comprising a storage device, a module calculating unit and first and second dividers, a switching unit and a two-channel switch, connected in a certain way and performing coherent processing of the original samples.

EFFECT: technical result is higher efficiency of extraction of signals of moving targets.
