基于随机水面阵列构形的水下GPS定位算法

Underwater GPS positioning algorithm based on randomly distributed buoys

水面阵元漂移引起的活动式水面阵最优跟踪几何构形改变是水下GPS系统中存在的普遍问题。本文提出了一种可动态地适应水面阵几何构形变化和水下目标运动的定位算法。较之于目前国际上采用的遥控锚定或自推进阵元方法,该方法有利于发挥水下GPS系统水面阵的固有优点,以增加水面阵元数量为代价降低了定位测量复杂程度,提高了测量的可实施性。

In GPS underwater positioning system, the randomly altering of the buoy array's tracking geometric configuration due to buoy drifting deteriorates its positioning properties. To adapt the system to buoy drifting, a weighted mean underwater positioning algorithm is put forward which is characterized by making full use of the inborn properties of the buoy array compared with the remote control self-propelled or anchored buoy solutions.
