水下便携式可应答同步编码声源系统研究

本文针对当前及未来多型水下航行体的通用化水下高精度定位跟踪及综合测控要求,开展小型便携式水下声源系统研究,解决了不同水下航行体定位跟踪及水声遥测与遥控的综合测控集成化问题,以及小型水下航行体的通用化声源安装适配性等难题。采用集成化一体式综合设计方案,功能上兼顾水声定位跟踪、水声遥测遥控等功能,性能上其短基线水声定位精度可达R×5‰(R为斜距),远程水声遥测遥控误码率为10-5。本文在系统总体方案中平衡了小尺寸与高性能之间的传统矛盾,大幅缩减声源尺寸和重量,并完成了小型水下滑翔机湖上试验。试验结果证明,该声源系统在比国外类似产品更小尺寸和重量的基础上,同时具备水声定位跟踪和水声遥测遥控等综合测控功能,可为多型水下航行体湖海试验提供高精度实时定位测量及远程应急遥控手段,具有较高的实用价值和良好的市场应用前景。

Research on Underwater Portable Responsible Synchronous Coding Sound Source System

In view of the current and future requirements of universal underwater high-precision positioning and tracking and integrated measurement and control of various underwater vehicles,a small portable underwater sound source system is studied.To solve the problem of integrated measurement and control of positioning and tracking of different underwater vehicles and underwater acoustic telemetry and remote control,and solve the problems of universal sound source installation and adaptability of small underwater vehicles.In terms of performance,the short baseline underwater acoustic positioning accuracy can reach R×5‰(R is the slant distance),and the error rate of long-range underwater acoustic telemetry and remote control is 10-5.The overall scheme of the system balances the traditional contradiction between small size and high performance,greatly reducing the size and weight of sound source.A small underwater glider was tested on the lake.The test results show that the sound source system has the functions of integrated measurement and control such as underwater acoustic positioning and tracking and underwater acoustic telemetry and remote control on the basis of smaller size and weight than foreign similar products.It can provide high-precision real-time positioning measurement and remote emergency remote control means for multi-type underwater vehicle lake sea test,and has high practical value Good market application prospect.
