Paper Abstract

Spaceborne microwave radiometer is an important remote sensor in acquiring information of the earth's surface. That its behavior is good or bad affects directly the success or failure of the whole satellite. Because analysis and test directly in real system will take very large risk and price digital simulation becomes an effective measure. This paper advances a basic idea and goals of digital simulation study of spaceborne microwave radiometer. The mathematical models of all sections in total-power microwave radiometer are built. And the simulation study of total-power microwave radiometer has been done. In simulation test discrete fast Fourier transform is used in signal processing. The simulation results prove that the models are accurate and effective. Also the result lay a foundation for the advancement of realizing spaceborne environment simulation test.
