Abstract
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.
