| 中文摘要: |
| 作为深海中重要的声传播途径之一,可靠声路径声道下的噪声级较低,声速剖面变化和海底界面作用对其影响较小。此外,当接收水听器位于该声道下时,可实现对近海面中近距离目标的无盲区监测。因此,可靠声路径必将成为一种重要的探测与定位途径。本文从可靠声路径的声传播特性着手,概述了国内外研究现状,逐步探讨结合各声传播特性所开展目标定位技术。旨在回顾当前各项技术成果并展望基于可靠声路径的目标定位技术今后的发展趋势。 |
| 英文摘要: |
| Reliable acoustic path is one of the important sound paths for deep water acoustic propagation. The sound velocity fluctuation and seabed interface have little influence on the sound propagation, and the noise level under this sound path is lower than others. Besides, when receiver is located in the channel, it can monitor the near surface target at medium range. So, the advantage of the reliable sound path will make it become one of the main ways for target exploration and localization in deep water. This paper mainly summarizes the domestic and foreign research on the reliable acoustic path, and focuses on the target location method. The aim of this paper is to review the current technical achievements and forecast the future development trend by reviewing the domestic and foreign target localization technology under reliable acoustic path. |
