The Modeling Analysis of Microwave Emission From Stratified Media of Nonuniform Lunar Cratered Terrain Surface for Chinese Chang-E 1 Observation

In China's first lunar exploration project, Chang-E 1, the multichannel (3.0, 7.8, 19.35, 37 GHz) microwave radiometers were aboard the satellite, with the purpose of measuring microwave brightness temperature from the lunar surface and surveying the global distribution of lunar regolith layer thickness, and global evaluation of

He content. To analyze the modeling of microwave radiative transfer from three-layered media of the lunar surface, some factors, such as the cratered lunar surface roughness and scattering of regolith particulate medium with temperature profile, are discussed. The three-layer model makes the predominance of the parameters, such as the regolith layer thickness and stratified structures, to be studied.
