单信标水声定位技术研究现状及应用展望

Research progress and prospect of acoustic positioning technology based on single beacon

针对未来水下载体长航时、远距离和高精度的定位需求,分析了传统长基线和超短基线等传统水声定位技术应用特点,指出了单信标水声定位技术在全球海域定位中的应用优势。详细介绍了基于虚拟长基线与位置跟踪两大类单信标水声定位方法及其研究进展,概括分析当前单信标水声定位技术现状,并结合水下定位、导航及授时体系建设需求,对单信标水声定位技术应用前景进行展望。

Aiming at the positioning requirements of long-endurance, long-distances and high-accuracy to underwater vehicle,the paper analyzed the application characteristics of traditional long baseline and ultra-short baseline underwater acoustic positioning technology, and pointed out the application advantages of positioning technology based on single beacon in global sea area positioning in the future. In the paper, the principle and research progress about virtual long baseline and position tracking,which were two kinds of acoustic positioning method based on single beacon, was introduced in detail, and the current situation of acoustic positioning technology based on single beacon was summed up and analyzed. Finally, combined with the construction requirements of underwater Positioning, Navigation and Timing(PNT) system, the application development of acoustic positioning technology based on single beacon was prospected.
