FIELD: radar.
SUBSTANCE: group of inventions relates to the methods and systems for electronic protection of active radars from active noise interference. In a system with dedicated compensation channels, dynamic weighting coefficients are used, obtained by interpolating estimates of the weight vector calculated from the active noise signal outside the spectrum of the radar signal.
EFFECT: increasing the efficiency of compensation for active noise interference acting on the side lobes of the radiation pattern of an all-round radar with a continuous or quasi-continuous signal and mechanical rotation of the antenna.
