FIELD: radar equipment.
SUBSTANCE: invention can be used in coherent-pulse radar systems for separation of signals of moving targets against background of passive interference with unknown Doppler phase. In the passive interference rejection filter, the output of the synchronous generator is additionally connected to the synchronous inputs of quadrators, an adder and a square-root extraction unit. Inputs of the passive noise rejection filter are inputs of the third delay unit, and outputs of the second complex adder.
EFFECT: high efficiency of rejection of passive interference with a priori unknown Doppler phase and separation of signals from moving targets.
