Abstract
Изобретение относится к средствам формирования радиометрических изображений в пассивной радиолокации. В способе формирования радиометрических изображений по циклическому алгоритму, который состоит из фаз калибрования по первому и второму эталонам, циклу накопления, фазы обработки и фазы преобразования данных, последовательно выполняют фазу обработки и фазу преобразования данных, которые следуют за циклом накопления, а выполняемые в любом порядке фазы калибровки предшествуют циклу накопления, при этом радиометрическое изображение в виде круга формируется за счет механического вращения с постоянной скоростью вокруг своей оси многолучевой антенны с частотным расщеплением направлений приема при просмотре в пространстве сектора телесных углов конической формы. Антенна содержит опорное устройство, электромеханический привод, волноводный переход, который поворачивается, компенсатор углового момента, планарный диэлектрический волновод, двумерную дифракционную решетку, облучатель-переход, а также датчик положения. Планарный диэлектрический волновод и двумерная дифракционная решетка находятся в электродинамической связи в полосе рабочих частот антенны и при разделении этой полосы на М, где , узких полос в пространстве образовывается М-лучевая диаграмма направленности веерной формы с М лучами. Изобретение обеспечивает повышение точности воспроизведения радиотеплового рельефа для поля наблюдения при одновременном достижении высоких чувствительности и пространственного разрешения.
