摘要
介绍了应用频率在10-90GHz波段的星载微波辐射计定标热源的结构及其功能;论述了定标热源微波吸收材料选择、吸收体结构设计、热设计及温度测控等技术与方法;给出了定标热源吸收率和温度特性测试结果。地面和在轨运行均表明,该定标热源满足星载微波辐射计设计要求。
In this paper,structure and functions of a Calibration Hot Target for Spaceborne Microwave Radiometer (the frequency range from 10 GHz to 90 GHz) is presented. Material selecting, structure designing of absorber, thermal designing as well as temperature measuring and controlling are also described and absorb rate and performance testing results the temperature are presented. The data of ground and orbit operation shows that the Calibration Hot Target accorded with Microwave Radiometer design.
