Detection of lunar soil thickness is to explore one of the important goals of the moon , the inversion of the the regolith thickness need to establish the accuracy of microwave radiation brightness temperature model . The lunar surface physical temperature distribution of the key parameters of the model . Lunar surface physical temperature is a function of the change with the latitude and longitude of the lunar surface , depth and time . From heat conduction theory , calculate the monthly scholars before combining the physical model of the surface temperature , heat conduction model proposed improvements to solve the lunar surface temperature . Followed by the parameters of the precise derivation and calculation model of the solar irradiance and Earth radiation and lunar internal heat elaborates solving the heat conduction equation numerical calculation methods and processes , thermal conductivity , heat capacity , the lunar soil density other various parameters on the model to calculate the error generated by the temperature . By comparison with the Apollo landing areas measured results and the results of the literature , the calculation results show that the model can be used to reflect the surface temperature distribution of the full month . In this paper, two lunar terrain correction of physical temperature model for the topography of the lunar surface will produce mutual occlusion affected by solar radiation , the dramatic changes in the lunar surface temperature . Finally, the measured laser altimeter data to carry out a preliminary calculation of the temperature . The results show that the cause can not be ignored : the topography of the lunar surface would lunar surface physical temperature .
