- Abstract
microwave remote sensing has become an important method of space exploration. In Chinese lunar exploration project, a microwave radiometer has been installed on Chang’E-1 satellite to investigate the microwave radiation properties of lunar surface and to assess the depth of lunar regolith. It is the first time that microwave remote sensing technology was appllied to detect the moon on lunar orbit. Due to its first application in deep space exploration, there are still some remained theoritical problems to be systematically solved, which include to research the microwave radiation transfer properties and to set up the suitable model to inverse lunar regolith depth. In this paper, the physical properties of the lunar surface influencing the brightness temperature were comprehensively discussed. The physical temperatures of lunar surface and of subsurface were simulated. A multi-layer model was presented to simulate the microwave brightness temperature and inverse the depth of lunar regolith. By applying the fluctuation dissipation theorem, the brightness temperatures obtained from four frequency channels were simulated based on multi-layer model at different latitude at noon and in midnight respectively. The simulated results closely accord with the results by the method of Wentzel-Kramers-Brillouin. It is indicated that the multi-layer model proposed in this paper is reasonable.
