FIELD: radio engineering, communication.
SUBSTANCE: signal reflected from a target is detected by filtering the received signal matched with a probing signal, followed by selection of the envelope and comparing with a detection threshold. The detection threshold is set in accordance with the level of interference measured by filtering the received signal, matched with pulse interference, based on interference reduction during filtering, matched with the probing signal.
EFFECT: high protection of radar stations from high-power pulse interference of a known structure.
