多标声学组合定位导航方法

Integrated acoustic positioning and navigation approach based on multi-beacon

为解决超短基线在远距离处定位导航绝对精度差的问题,提出一种长/超短基线组合声学定位导航方法.运用最小均方误差准则,对长基线和超短基线的定位结果进行信息融合.理论推导和仿真试验均表明:该方法提高了定位导航精度,扩大了作用区域,其性能优于长基线定位导航系统.

An integrated long/ultra-short baseline（L/USBL） location and navigation approach was developed to solve the poor resolution of the location and navigation with ultra-short baseline at long range. Long baseline and ultra-short baseline information was fused based on the minimum mean square error criterion. Both theoretical derivation and simulation indicate that the proposed approach improves navigation and positioning accuracy while extending the operating region, and its performance is superior to long baseline system.
