To get the lunar regolith thickness, the surface effective reflectivity is one of the essentially influential factors. The moon surface is rather rough, and the proper reflectivity model is constructed essentially for the rough surface. Therefore, according to the spatial resolution of the microwave radiometer data onboard the Chang’E-1 lunar satellite, the surface roughness model is constructed with the corresponding laser altimeter data. Then the effective reflectivity of the lunar surface is calculated based on the Q/H model. The distributions of vertical and horizontal effective reflectivity for rough lunar surface are also presented assumed that the view angle is 30°. The results indicate that the lunar surface roughness has great influence on its effective reflectivity.
