三度体重力归一化总梯度的计算方法

ALGORITHM OF NORMALIZED TOTAL GRADIENT OF THREE DIMENSIONAL BODY OF GRAVITY

本文在前人研究的基础上对三度体归一化总梯度做了新的探索，提出应用快速傅氏变换实现重力三度体归一化总梯度的计算方法，通过对单一形体模型和叠加形体模型的计算，取得了较好的效果。

On the previous researches into the method of Normalized Total Gradient (NTG), a new calculating technique has been developed, namely, implementation of NTG of three dimensional body of gravity by FFT. It has testified to be effective to use NTG to interpret three dimensional body.
