摘要

摘要: 针对水声定位系统是水中兵器试验或水声对抗任务所必须的基础测量系统, 提出了基于水平非等距线阵定位技术、相关波门修正时延差等技术设计鱼雷水声同步定位系统的快速定位算法, 介绍了该算法的工作原理和实时轨迹修正方法。经Matlab仿真对比验证表明该算法正确可行。该非等距线阵定位系统具有布阵灵活、经济可靠等优点, 可在更广泛的阵元载体平台上安装使用, 为设计鱼雷中远程、短基线或超短基线水声定位系统提供借鉴。

Abstract: Underwater acoustic positioning system is a basic measurement system for underwater weapon test or under-water acoustic countermeasure mission. This paper presents a fast positioning method for designing underwater acous-tic synchronous positioning system for a torpedo based on horizontal non-equidistant line array positioning technology, correlation window corrected time-delay difference technology, etc., and introduces its principle and the real-time tra-jectory amendment method. Simulation with Matlab shows that this algorithm is feasible and correct. This non-equidis-tant line array positioning system has the advantages of flexible array deployment, and is economical and reliable, so it can be mounted on a wide range of array element carrier platforms. This study may provide a reference for designing torpedo’s underwater acoustic positioning systems with medium or long distance, and short or ultra-short baseline.
