Design of a Fast Adaptive Shipborne Hydroacoustic Positining System

摘要:

提出一种可快速布置、自动适应阵型、基于同步信标的高精度船载短基线水声定位系统。该定位系统采用柔性短基线四元阵，可布置在各型试验船或测量船，利用回波测距，自动计算出试验船上 4 个声基元布放点的坐标位置关系，再结合双天线卫星罗经的 GPS 高精度定位、定向数据，快速生成短基线阵在大地坐标系中的位置。描述了该定位系统的系统原理、组成和工作过程，并完成了一套用于湖上试验场的定位系统，试验效果较为理想。

Abstract:

This paper presents a high-precision shipborne short-baseline(SBL) hydroacouostic positioning system based on synchronization beacons that can be quickly deployed and automatically adapted to the acoustic array. The positioning system adopts a flexible SBL fort-element array，which can be arranged on various types of test ships or survey vessels. The echo array algorithm is used to calculate the coordinate position relationship of the 4 acoustic element placement points on the test ship. Combined with the high-precision positioning GPS and orientation data from dual antenna satellites compass，the position of SBL array in the geodetic coordinate system can be quickly generated. This article describes the system principle，composition and working process of the positioning system，and completes a set of positioning system for the lake experimental field，the test results of which are relatively matched.
