Status and Prospect of Satellite SAR Antenna Thermal Control Technology

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 technology 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.
