水下声学主动定位技术及其在载人潜水器上的应用

Study on the Active Underwater Acoustic Positioning Technology and Its Application in Manned Submersibles

水下声学主动定位技术通过声应答的方式实现水下目标定位,主要分为长基线、短基线和超短基线等三种定位系统。它是海洋开发领域中的一个非常重要的组成部分,为水下目标探测、定位跟踪、海底地形勘探和水下遥控作业等各种高精度工作提供技术支持。在探讨以上三种水下声学主动定位技术的同时,并以"蛟龙号"为例,分析其在载人潜水器上的应用。

The active underwater acoustic positioning technology can achieve underwater target positioning by the means of sound response. It can be mainly divided into 3 kinds of positioning systems： the long baseline （LBL）, short baseline （SBL） and ultra-short baseline （USBL）. As a significant technology in the field of marine development, it provides technical support for various high-precision tasks, such as underwater target detection, positioning and tracking, seabed topographic survey and underwater remotely controlled operations. This paper discusses the 3 kinds of active underwater acoustic positioning technologies, and takes the ＂JiaoLong＂ as an example to analyze their aPPlications in manned submersibles.
