Abstract对微波辐射计的两种定标方法进行了介绍,即分步定标法和整体定标法.分步定标法需要测量的中间参数较多,故误差来源多,定标精度低.整体定标一次完成,没有中间环节,因此定标精度较高,缺点是要求有一个提供给天线的准确、可靠的噪声环境,成本较高.
Other AbstractIn this paper ,structure and functions of a Calibration Hot Target for Spaceborne Microwave Radiometer (t he f requency range f rom 10 GHz to 90GHz)is presented.Material selecting,structure designing of absorber,thermal designing as well as temperat ure measuring and cont rolling are also described and absorb rate and performance testing results the temperat ure are presented.The data of ground and orbit operation shows that the Calibration Hot Target accorded with Microwave Radiometer design.
