声速分布深海超短基线定位算法

Positioning Algorithm of Deepwater USBL for Random Distributed Velocity of Sound

超短基线定位系统因其基线基阵尺寸小,易于安装而常被用于海洋科学领域,而改进深海条件下,长程超短基线的定位算法以求得到更高的定位精度势在必行。以超短基线定位原理及传统的超短基线定位算法为引子,提出了一种简便的可用于任意声速分布的定位新算法,并通过计算机仿真比较验证了该算法的有效性。

Ultra-short baseline system （USBL） is spread used in Ocean scientific field because of its small aperture size and easily being installed. It was aimed to improve positioning algorithm of long range USBL under the deepwater condition for the sake of higher positioning precision. After discussing the theory of positioning of USBL and conventional algorithm, a simple and convenient new positioning algorithm which could be used for random distributed velocity of sound was proposed. The simulation results prove its correctness.
