星载合成孔径微波辐射计的反演公式

The Reconstruction Formula of Synthetic Aperture Microwave Radiometer on Satellite

本文利用相关理论对星载合成孔径微波辐射计(简称SAMR)进行了详细的分析和探讨,给出它对地物辐射响应的一般表达式.当地物辐射源为非相关时,得到窄带SAMR对地物亮温度分布的反演公式.当地物辐射源为相关时,论述了辐射计的输出不含地物亮温度分布有用信息.

This paper inquires in detail the synthetic aperturemicrowave radiometer(SAMR) on satellite according to the coherent theory, and presents the generalexpression for the SAMR respones to the earth's radiation. When the earth's radicationsource is incoherent, the formula for reconstructing the earth's brightnesstemperature distribution is derived for the narrow- band SAMR. When the earth's radiation soure is coherent, the SAMR outputs do not include the usefrulinformation about the earth's brightness temperature distribution.
