Modeling, simulation, inversion and Chang E-1 data validation for microwave emission remote sensing of lunar surface media

In China´s first lunar exploration project, Chang-E 1 (CE-1), a multi-channel (3.0, 7.8, 19.35 and 37GHz) microwave radiometer in passive microwave remote sensing, was first aboard the satellite, with the purpose of measuring microwave brightness temperature (Tb) from lunar surface and surveying the global distribution of lunar regolith layer thickness. In this paper, some works on this mission, including the microwave emission modeling and Tb simulation of lunar surface media, CE-1 data validation and retrieval of lunar regolith layer thickness from multi-channel CE-1 Tb data, and evaluation of global inventory of Helium-3 in lunar regolith, are reported.
