Abstract
Изобретение относитс к радиотехнике. Цель изобретени - независимое формирование остронаправленной и всенаправлен- ной с провалом в заданном направлении диаграммы направленности (ДН). Кольцева антенна решетка содержит излучатели 1, диаграммообразующую схему (ДОС) 2, фиксированные фазовращатели 3, блоки 4 и 7 независимого управлени фазой по входу и выходу, многоканальный делитель 10 мощности . Заданную ДН можно сформировать, изменив амплитуду и фазу возбуждени входа ДОС 2, реализующего синфазное распределение волн в излучател х 1. При соответствующем изменении коэффициента св зи блока 7 и сдвигов фаз управл емых фазовращателей 6 блока 4, соединенного с синфазным входом ДОС 2, обеспечиваетс независимое формирование остронаправленной и всенаправленной ДН с провалом в заданном направлении на прием и передачу . 2 ил.The invention relates to radio engineering. The purpose of the invention is the independent formation of a highly directional and omnidirectional with a failure in a given direction of the radiation pattern. The ring array antenna contains emitters 1, a beam forming circuit (DOS) 2, fixed phase shifters 3, blocks 4 and 7 of independent phase control of the input and output, a multichannel power divider 10. A given DN can be formed by changing the amplitude and excitation phase of the DOS 2 input, which implements the in-phase distribution of waves in radiators 1. With a corresponding change in the coupling coefficient of block 7 and phase shifts of controlled phase shifters 6 of block 4 connected to the common-mode DOS 2 input, independent the formation of highly directional and omnidirectional NAM with failure in a given direction to receive and transmit. 2 Il.
