FIELD: radar signals.
SUBSTANCE: invention relates to radar and can be used to develop and upgrade devices for processing phase-shift keyed radar signals. The technical result is to increase the resistance to interference at frequencies close to the carrier frequency of the echo signal. This result is achieved by the fact that the device for Doppler processing and compression of phase-shift keyed radar signals (71) contains a gating circuit (1), a memory device (2), suboptimal filters (30÷3N-1 ), where
is the number of Doppler channels, a Doppler accumulation unit (4), a reference signal generator (5) and weight processing units (6), as well as the fact that two devices for Doppler processing and compression of phase-shift keyed radar signals (72 and 73) and an amplitude comparison device (8).
EFFECT: increase in the resistance to interference at frequencies close to the carrier frequency of the echo signal.
