摘要
搭建了一套水下录音记录系统,在复杂浅海环境进行了水声数据采集实验;对于水声采集数据进行了距离、频率谱分析,利用MIT开发的声学计算程序OASES针对声场进行了仿真分析。通过模拟结果和实测结果的比较,优化调整仿真程序的环境参数,分析发现影响声场分布的主要因素为沉积层压缩波声速与声源深度。通过这种方式,优化了仿真软件的环境参数,初步建立了比较准确的浅海水声环境仿真模型,取得了预期实验效果。
In this paper,an underwater acoustic data acquisition test is conducted in complex shallow water environment by building an underwater recording system.Distance and frequency spectrum analysis of underwater acoustic data acquisition is carried out,and simulation analysis of sound field is carried out by using the acoustic calculation program OASES developed by MIT.By comparing the simulation results with the measured results,the environmental parameters of the simulation program are adjusted continuously.It is found that the main factors affecting the distribution of sound field are sound velocity of compressed wave in sedimentary layer and the depth of sound source.In this way,the environmental parameters of the simulation software are optimized,and a relatively accurate shallow water acoustic environment simulation model is preliminarily established,and the test results are achieved.
