NOISE REJECTION FILTER Russian patent published in 2025 - IPC H03H17/02 H03H21/00 H04B1/12 

FIELD: radar equipment.

SUBSTANCE: invention relates to radar equipment and can be used in coherent-pulse radar systems for separation of signals of moving targets against background of passive interference with unknown correlation properties. In the noise rejection filter, the output of the synchronous generator is connected to the synchronous inputs of the complex interface unit, the second complex multiplier, accumulators, the module calculating unit and dividers. Inputs of the noise rejection filter are inputs of the second delay unit, and outputs of the complex adder.

EFFECT: high efficiency of rejection of passive interference with a priori unknown correlation properties and separation of signals from moving targets.
