DEVICE FOR ADAPTIVE PROTECTION OF A RADAR STATION FROM ACTIVE NOISE INTERFERENCES WITH AN ARBITRARY SPATIAL SPECTRUM AND A DIFFERENT POLARIZATION STRUCTURE Russian patent published in 2020 - IPC G01S7/36 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to radio electronics, specifically to signal processing and detection devices with background of active noise interference with arbitrary spatial-polarization structure. Invention is based on application of combined spatial-polarization processing with factorization into separate types of processing. Distinctive feature is the averaging and analysis device addition and the spatial adaptive filters control device after the subchannel diagrams beamformers, which enables based on analysis of received electromagnetic oscillations in the area of angular coordinates corresponding to the zone of side lobes of the beam pattern of the antenna system, determine presence or absence of active interference in the given region and include spatial adaptive filters in processing of received signals in case of necessity – only in case of interference.

EFFECT: high detection efficiency and reduced computational costs in case of absence of active interference acting in side lobes of the beam pattern of the antenna system.
