FIELD: radio engineering; methods of detection of interference signals; detection of presence of interference at input of receiving device of coherent radar station. SUBSTANCE: used as indication of interference is information on jump-like change in signal phase in transit from receiving the target signal to receiving the interference signal instead of speed and acceleration of target (or simultaneously with these factors). EFFECT: enhanced noise immunity of radar station.

Изобретение относится к области радиотехники, в частности к способам обнаружения помеховых сигналов, и предназначено для обнаружения факта наличия помехи на входе приемного устройства когерентной радиолокационной станции (РЛС). Целью изобретения является повышение помехозащищенности РЛС. Эта цель достигается тем, что в качестве признака помехи вместо скорости и ускорения цели (или одновременно с ними) используется информация о скачкообразном изменении фазы сигнала при переходе от приема сигнала цели к приему сигнала помехи.The invention relates to the field of radio engineering, in particular to methods for detecting interference signals, and is intended to detect the fact of interference at the input of a receiver of a coherent radar station (radar). The aim of the invention is to increase the noise immunity of the radar. This goal is achieved by the fact that instead of the speed and acceleration of the target (or simultaneously with the target), information about the abrupt change in the phase of the signal during the transition from receiving the target signal to receiving the interference signal is used as a sign of interference.
