摘要
介绍了重力梯度仪的测量原理,提出在潜航器上配备重力梯度仪,利用其对距离变化敏感的特性,通过连续的观测,可以探测出载体有效机动范围内存在的障碍物,并实现避碰,从而保证潜航器在水下的安全航行。
The paper introduced the measurement principle of the gradiometer.A new method of gradiometer equipped on the vehicle and using the character of sensitivity to the distance of the gradiometer is proposed.By continuous measurement we can calculate whether the barrier exist around the vehicle.From the result,vehicle can change the track before it collide the barrier,so it can ensure the safety of the vehicle which is moving underwater.
