Application of Gravity/Topography Admittance to the Inversion of Lunar Geophysical Parameters Considering the Lithosphere as a Thin Elastic Spherical Shell

Because of the Apollo lunar seismic network merely located on the near side of the Moon and the traditional methods failing in the best solutions，several lunar parameters such as load ratio f，crustal thickness bc，subsurface load depth Zb，crustal density pc，lithospheric elastic thickness Te can be solved through lunar gravity/topography admittance with PSO. Results indicate that surface and subsurface load models are rational and all the best solutions of the lunar parameters studied can be simultaneously calculated. It can provide a reference for lunar internal structure research，when such method investigated here applied to lunar geophysical parameters inversion.
