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 rejection filter, the output of the clock generator is connected to the clock inputs of the complex conjugation unit, the complex multiplier of the Doppler phase meter, accumulators, the module calculation unit and dividers. The inputs of the noise nullification filter are the inputs of the second delay block, and the outputs are the outputs of the complex adder.
EFFECT: increasing the efficiency of nullification for passive interference with a priori unknown Doppler phase and the selection of signals from moving targets.
