摘要
介绍两种典型的星载SAR天线 :SIR C成像雷达的有源微带相控阵天线和Radarsat 1的波导缝隙相控阵天线。报导了近年来星载SAR天线在多波段、多极化阵列天线 ,集成化、固态化、模块化有源相控阵天线 ,超轻型充气式阵列天线和双波段、双极化共孔径阵列天线等方面的研究进展 ,并给出了一些天线的参数。
This paper presents two typical spaceborne SAR antennas: microstrip active phased array antenna of SIR-C image radar and slotted waveguide phased array antenna of Radarsat-1. It also introduces the recent development for spaceborne SAR antenna in such aspect as multi-band multi-polarization array antenna, integrated, solided and moduled active phased array antenna, super low mass inflatable array antenna and dual-band dual-polarized shared-aperture array antenna, and etc.. Furthermore the parameters of some antennas have been given in this paper.
