超短基线水下声学定位数据处理

Ultra-short Baseline Underwater Acoustic Location Data Processing

该文在介绍超短基线定位原理的基础上,依据水下目标x、y、z3向在时间轴上各自的分布来识别定位跳点、并采用合理的数据结构与算法,实现对跳点的交互式剔除,从而得到可信的水下声学定位数据。最后介绍了基于航位推算的定位数据匹配方法,提升水下声学定位数据的效率,以满足现场作业中对水下定位的更高需求。

This paper introduces the ultra short base line （USBL） positioning theory, recognizes the tmderwct- ter destination＇ s jumping positioning points according to maps between x, y, z and time series, uses reasotia- ble data structure and algorithm to realize interactive elimination, and gets reliable underwater acoustic positis- ning data. Finally, to satisfy more accurate and different frequency sensors position data Match demand, this paper introduces the method of position data match based on dead reckoning.
