摘　　要：提出了基于重力梯度测量对海底障碍地形探测的方法,并以一锥形海底地形为例计算其在各个方向上引力的大小,从目前重力梯度仪的测量精度来看完全满足探测的要求。验证了本方法的可行性。A new method by using the character of the submarine topography will engender gravity gradient is proposed.An example of calculate the gravity gradient of a subulate topography is given,from the example can find that the gravity gradient aroused by the barrier is very big and can easily be observed by the current gradiometer,the result proved the method of this paper is feasible.This study provides a new method for the underwater carrier to avoidance collision,and the method has passive and all-weather characters.
