摘要
介绍了国外多种合成孔径雷达卫星天线的热控方式,并结合具体的工程实践讨论了微带阵、波导阵形式合成孔径雷达卫星天线热控设计过程中面临的一些问题,以及解决问题的途径,针对微带阵天线的试验表明其热控设计能够满足天线在轨热控的要求。
This paper introduces the thermal control modes of several satellite-borne SAR antennas and then presents the means of thermal control design for a satellite-borne SAR antenna. The problems that may appear in the process of design are discussed. The method that may solve these problems is also given at last. The experimental results of the micro-strip array antenna shows that the thermal control design can meet the specified requirements.
