摘要
为利用船舶环境噪声对海洋环境进行反演,实现对任意复杂海洋环境的探测,本文以噪声传播连续波动方程为基础,建立基于流体的噪声振动衰减模型,并采用MATLAB软件对其进行编程计算,研究不同海洋环境对噪声谱的影响。计算结果表明:本文建立的海洋环境噪声模型对不同的设计工况均有较大的灵敏度,可为实际应用提供参考。
In order to make use of the ocean environment noise to carry on the inversion to the marine environment,and realize the exploration of any complex marine environment. In this paper,a model based on the noise propagation of continuous wave equation is established,and the model of the vibration attenuation of the fluid is established,and the influence of different marine environment on the noise spectrum is studied by using MATLAB software. The calculation results show that the model of the marine environment has great sensitivity to different design conditions,which can provide reference for practical application.
