摘要
Based on the high degree lunar gravity field models LP150Q,GLGM-3 and SGM150j,and Chang′E topography model CLTM-s01,the localized gravity/topography admittance and correlation for various gravity field models within an axisymmetric window of fixed widths in the spectral domain are studied.Localized gravity/topography admittance and correlation for some typical mascon basins are also investigated.The results firstly show that the power spectra of the lunar gravity field from medium-to high-frequency can be increased after adding the lunar farside gravity field data.Moreover,all the models are appropriate for localized gravity/topography admittance and correlation analysis on the near side of the moon,which indicates that all the models can be used to estimate the localized geophysical parameters on the nearside.As to estimation of localized geophysical parameters on the farside,however,SGM150j is quite suitable.Finally,there is more mass anomaly in the main mascon basins on the nearside than those on the farside and such mass anomaly comes deeper than that on the farside.
