舰船辐射噪声指向性统计模型及分析方法
Statistical model and analysis method for spatial directional distribution of ship radiated noise
摘要
Abstract
To investigate the spatial distribution characteristics of the ship target's radiated noise, this paper takes the noise directivity of a single vertical section as an example to establish the statistical model for directivity of ship target's radiated noise based on the robust regression analysis theory and actually measured data. The verification study for aforementioned model and method is carried out based on corresponding statistical analysis method and the analysis of the data acquired on the sea. The research results showed that the statistical model and analysis method are simple, practical and reliable, having a wide application scope, and they are very helpful to investigate and e⁃valuate spatial characteristics and statistical rules of underwater radiated noise originated from various ship targets under different sailing conditions and test circumstances.关键词
