摘　　要：随着大功率星载SAR(合成孔径雷达)天线技术的发展,阵面设备量及热流密度越来越大,天线热控技术面临新的挑战,对新型热控材料及方法的需求变得愈加迫切。文中对星载SAR天线热控技术的研究现状进行了较全面的综述,针对天线结构形式、阵面发热量、工作模式等方面进行了系统的分析和评述,提出了为实现大功率、高热流密度的热控技术需解决的关键问题,并指出了未来天线热控技术进一步的研究方向。With the rapid development of high power satellite SAR antenna technology, the amount of antenna modules and their heat flux density are getting higher. Antenna thermal control technology is facing challenge. New thermal control material and method are more desired. The status of satellite SAR antenna thermal control technology is reviewed in this paper. Aspects such as structure type, antenna heat generation, operating mode are systematically analyzed and assessed. Some key problems about the realization of thermal control technolo- gy of high power and high heat flux density are proposed. This paper also provides the future research direction of the SAR antenna thermal control technology.
