Abstract

Предложены сферический отражатель, имеющий низкую стоимость, и антенная система с механическим сканированием, использующая такие отражатели. В системе используется один или более (по существу подобных) основных сферических отражателей (каждый имеет усеченную сферическую поверхность), каждый из которых имеет связанный подвижный облучатель, имеющий привод от двухосного механизма позиционирования, который имеет несколько перемещающихся частей. Структура облучателя может, предпочтительно, содержать волноводный облучатель с точечным источником совместно с вогнутым вспомогательным отражателем, который используется в конфигурации, подобной антенне Грегори для коррекции сферической фазовой ошибки. Механизм позиционирования перемещает конфигурацию типа Грегори для коррекции сферической фазовой ошибки. Механизм позиционирования перемещает волноводный облучатель и вспомогательный отражатель последовательно для того, чтобы сдвинуть положение направления луча в дальней зоне неба. После коррекции фазы с помощью вспомогательного отражателя полученный в результате сигнал, отраженный от основной апертуры, можно одновременно передавать и принимать на двух или более независимых частотах. С помощью сборки из таких многочисленных сферических отражателей, каждый из которых имеет подвижный облучатель, приводимый в движение своим собственным механизмом позиционирования, достигают компактного размещения. Сборку монтируют на круглой опорной плите и предпочтительно закрывают обтекателем.Отчет о международном поиске был опубликован 2000.01.27.
