非同步水声定位技术及其性能评价

Non-synchronous underwater acoustic location and it's performance evaluation

探讨用非同步方式进行水声定位的解算方法,用蒙特卡洛方法对各误差源及目标位置对同步及非同步定位系统定位精度的影响作了统计分析,并对其可行性及适用性进行了分析和探讨。仿真结果及湖试结果表明,采用长基线阵的非同步水声定位系统具有较高的定位精度。

This article probes the positioning models for non-synchronous forms, the effects of various error sources and the position of target upon positioning precision were analyzed with Monte-Carlo Method, and their feasibility and applicable scope were discussed. The simulation and lake experiment results indicate that the long baseline non-synchronous underwater acoustic system with buoys array can achieve better location precision.
