ADAPTIVE BAND-STOP FILTER Russian patent published in 2016 - IPC H03H7/12 

FIELD: radar and radio navigation.

SUBSTANCE: invention is intended for separation of signals of movable targets on background of passive jamming at wobbling repetition period of sounding pulses. Said result is achieved by adaptive rejection filter includes the first, second and third main delay units, first, second and third complex multipliers, a unit for measuring phase, the main weight unit, a unit of weight coefficients, main adder, a clock generator, first and second additional delay units, extra adder, an additional weight unit and a switch, connected to each other in a certain manner and which perform coherent processing of initial readings.

EFFECT: technical result consists in improvement of efficiency of extraction of signals of movable targets.
