船载式远程高精度水声定位系统

MOVABLE ACOUSTIC TRACKING SYSTEM

本文比较了各种水声定位跟踪系统的特点，由此可明显看出长基线模式的船载式水声定位跟踪系统将兼有使用方便、适用性强、定位精度高、作用距离远的优点，仔细分析了要实现这类系统的关键技术难题，介绍了我国自行研制的一个船载式远程高精度水声定位系统的组成和工作原理，该系统还率先突破了主动式水声定位系统中非模糊距离Ｒｍａｘ＝ＣＴ的原理性限制，使系统可进行远程。

This paper summarises a kind of Movable Acoustic Tracking System. It can effectively track five undewater targets at long distance with high sampling rate of the target and very high tracking precision, but there is not Multiple value problem of the target distance. The system have used a series of signal processing technology to increase the accuracy of time delay estimation, then under condition which the system is shipborne and only a small dimention of the base lime is used the system still have high performance.
