水下便携式应答定位系统设计与实现

Design and Implementation of the Underwater Portable Ultra-Short Baseline Positioning System Based on Response Principle

针对蛙人执行任务时水下便携高精度定位需求,设计一种小型便携式基于应答原理的水下超短基线定位系统。首先设计并分析应答式定位系统构架、工作原理以及定位原理;其次提出应答式定位系统硬件设计方案;再次,重点对应答定位系统的便携定位端和应答器软件进行详细描述;最后通过水池试验对水下便携式应答定位系统的有效性和稳定性进行测试。试验结果表明,该应答式定位系统具备水声应答定位功能,可为水下蛙人提供高精度应答定位测量手段。

Aiming at the requirement of underwater portable high-precision positioning when frogman performs tasks,a small portable underwater ultra-short baseline positioning system based on response principle is designed.Firstly,the architecture,working principle and positioning principle of the responsive positioning system are designed and analyzed.Secondly,the hardware design scheme of responsive positioning system is proposed.Thirdly,the portable positioning terminal and transponder software of the transponder positioning system are described in detail.Finally,the effectiveness and stability of underwater portable response positioning system are tested by pool test.The experimental results show that the responsive positioning system has underwater acoustic response positioning function,and can provide high-precision response positioning measurement means for underwater frogmen.
