Abstract
Способ защиты обзорной радиолокационной станции (РЛС) с фазированной антенной решеткой (ФАР) от помех, включающий формирование диаграммы направленности антенны (ДНА) с положением луча в текущем направлении зоны обзора и с положениями «нулей» ДНА в направлениях на источники помех на основе установленного распределения амплитуд и/или фаз токов по элементам ФАР, отличающийся тем, что в заданной части зоны обзора определяют направления на источники помех, в процессе осмотра зоны обзора для текущего направления в заданной ее части из заранее рассчитанных распределений амплитуд и/или фаз токов по элементам ФАР выбирают и устанавливают в ФАР распределение, в котором положение луча соответствует текущему направлению зоны обзора, а положения «нулей» ДНА - направлениям на источники помех.A method for protecting a surveillance radar (phased array) with a phased array (PAR) from interference, including generating an antenna pattern (BOTTOM) with the beam position in the current direction of the viewing area and with the positions of the "zero" BOTTOM in the directions to the interference sources based on the established distribution amplitudes and / or phases of currents for PAR elements, characterized in that in a given part of the viewing area, directions to sources of interference are determined, during the inspection of the viewing area for the current direction in a given part of it from before the calculated distributions of the amplitudes and / or phases of the currents over the PAR elements are selected and installed in the PAR, a distribution in which the position of the beam corresponds to the current direction of the viewing area, and the position of the “zeros” of the BOTTOM corresponds to the directions to the sources of interference.
