舰艇动态辐射噪声建模与仿真方法
Modeling and simulation method for dynamic radiated noise of warship
摘要
Abstract
A method for generating the dynamic radiated noise signals of warships based on the backpropagation neural network is proposed.This method overcomes the problem of the reduction of the flexibility and fidelity in self-propelled acoustic decoy radiation noise simulation.Based on the characteristic set and statistical features of the multispeed measured warship radiated noise frequency domain,the BP neural network and an empirical model were used to predict the speed-related characteristic parameters.Subsequently,dynamic parametric modeling was per-formed for the line spectrum,continuum spectrum,and modulation envelope components.The hearing filter cross-over band was used to determine the modulation parameters,and the continuum component was finely modulated,considering the auditory domain characteristics of ship-radiated noise.In this method,the"multidomain mapping and multidimensional feature fusion"mathematical model of radiated noise driven by the measured data was used to dynamically generate radiated noise at different speeds of the same warship.The simulation and experimental data processing results showed that the proposed method can generate simulated signals with high consistency with the measured data in terms of time-domain,spectral,and auditory features,thereby paving a technical pathway for en-hancing the underwater deceptive countermeasure capabilities of self-propelled acoustic decoys.关键词
