基于矢量水听器的浅海背景噪声分析方法研究

摘要

本文在研究浅海背景噪声场矢量理论的基础上, 通过对比不同季节、不同海洋气象环境下获取的长期观测数据, 提取海洋背景噪声矢量特征, 结合典型声压与振速频谱分析方法以及声压与振速比值谱分析方法总结不同季节、不同海洋气象环境下的规律, 并对风生海洋背景噪声谱特征进行了统计建模.%Based on the research of the shallow sea acoustic vector theory, the rules of different seasons and different marine meteorological environments are concluded by comparing the long-term observation data in different seasons and different marine meteorological environment, extracting the vector characteristics of ocean background noise and combining typical sound pressure and frequency spectrum analysis method and sound pressure and vibration velocity spectrum analysis method.Moreover, the statistical model of ocean ambient noise spectrum characteristics is established.
