神舟4号飞船多频段微波辐射计及其应用

Multi-frequency Microwave Radiometer on"SZ-4" Spaceship and Its Applications

介绍了我国首次研制的空间对地观测被动微波遥感器——神舟4号飞船多频段微波辐射计的设备性能参数及指标,并对海洋、沙漠等地物目标的测量结果进行了分析,与国外其它星载微波辐射计的测量结果进行了比较。

The multi-frequency microwave radiometer on 'SZ-4' spaceship is the first air-to-ground passive microwave sensor developed in China. In this paper, firstly, the performance parameters and indices of the radiometer are introduced in brief. Secondly, the measured data of ground objects are given and analyzed. On the basis of the data, we analyze the stability of the microwave radiometer. In addition, water content in atmosphere and the surface temperature regression model of desert are gotten from the data. Finally, compare the analysis results from the microwave radiometer mentioned above and other space-borne microwave radiometers. From the comparing results, we can come to a conclusion that the data from the microwave radiometer on 'SZ-4' spaceship are available.
