摘要

为了研究南海东北部声波传播特性的影响，利用 GEBCO08 全球地形网格数据和 Argo 数据对南海东北部受黑潮影响的两个站点的声波传播特性进行了数值模拟。分析了不同海洋环境对声波传输特性的影响。结果表明，在一定范围内增加声源的布放深度会减少传播损耗；在海面声道或深海声道轴线附近布放声源也会大大增加声信号的传播距离；海底山脉等地形的存在会增加传播损耗。

The Impact of Special Marine Environments Such as the Kuroshio on Hydroacoustic Detection Equipment

In order to study the impact of acoustic propagation characteristics in the northeastern South China Sea, GEBCO08 global terrain grid data and Argo data were used to numerically simulate the acoustic transmission characteristics of two stations in the northeast South China Sea affected by the Kuroshio. The impact of different marine environments on acoustic transmission characteristics was analyzed. The results show that increasing the deployment depth of a sound source within a certain range will reduce the transmission loss; deploying a sound source near the axis of the surface acoustic channel or the deep-sea acoustic channel will also greatly increase the propagation distance of sound signals; and the presence of topography such as undersea mountains will increase the transmission loss.

期刊介绍： Journal of Marine Science and Engineering (JMSE; ISSN 2077-1312) is an international, peer-reviewed open access journal which provides an advanced forum for studies related to marine science and engineering. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
