Acoustic Characterization of the Luzon Strait Based on LLC4320 Environmental Data
摘要
Abstract
Sound waves are the main means of underwater information acquisition and target detection,and their propagation characteristics and sound field distribution in ocean waveguides are closely related to the marine dynamic environment.Based on LLC4320 reanalysis data,an analysis of local environmental field characteristics and acoustic features for the Luzon Strait and its surrounding waters is conducted,and the applicability of high-resolution data for acoustic feature research is evaluated.Firstly,by analyzing the temporal and spatial changes of the temperature and salinity fields in the region in January,combined with the spatial distribution and temporal changes of the thermocline,the dynamic environmental characteristics of the Luzon Strait region is studied.Furthermore,research on the laws of sound propagation is conducted,and the correlation between sound velocity,sound propagation characteristics,and temperature and salinity fields is evaluated,which can provide references for the application of high-resolution ocean numerical simulation in the study of ocean acoustic features.关键词
