| 摘 要： | 从快速 Hartley变换 (FHT)基本概念入手 ,给出了 Hotine核在平面近似、球面近似、Molodenskii近似下的反演模型。另对 FHT处理中所需的坐标转换以及边缘效应等问题加以讨论。同时 ,为了改善长波特性的重力场信息 ,利用 M阶次的参考重力场对上述 Molo-denskii模型进行了改化。

| Abstract: | Based on the theory of fast Hartley transform(FHT),the inversion of Hotine formula is discussed in detail from planar approximation,spherical approximation,Molodenskii like approximation in this paper And the author analyses the problem of coordinate transform and edge effect in processing FHT Meanwhile,the inverse Hotine formula is modified with a satellite derived reference gravity field up to degree and order M in order to minimize the long wavelength biases |
