Based on the description of the spherical wavelet theory, this paper has induced and compared several kinds of spherical wavelets, analysed the newest Earth Gravity Model@P1EGM 96 and, on such a basis, used multi resolution analysis of spherical wavelets to calculate the global free air gravity anomaly and gravity geoid, with an explanation given on the proceesing result.
在介绍球面小波理论的基础上 ,推导和比较了几种球面小波 ,分析了最新地球重力模型———EGM 96,以此为依据 ,把球面小波多分辨分析用于计算全球自由空气异常及重力大地水准面 ,并对处理结果做出解
