FIELD: radar engineering.
SUBSTANCE: used in coherent-pulse radar systems for extracting signals from moving targets against the background of passive interference with an unknown Doppler phase. In the noise suppression filter, the output of the sync generator is additionally connected to the sync inputs of the first multiplier, the second multiplier, and the adder of the first channel and to the sync inputs of the first multiplier, the second multiplier, and the adder of the second channel. The inputs of the noise suppression filter are the inputs of the second delay block, and the outputs are the outputs of the complex adder.
EFFECT: increasing the efficiency of suppression for passive interference with a priori unknown Doppler phase and the selection of signals from moving targets.
