Analysis of acoustic concealment of underwater vehicles based on the acoustic radiation characteristics of underwater structures
To study the acoustic stealth performance of autonomous underwater vehicles(AUV),an analysis of the structural sound radiation characteristics was conducted,focusing on the acoustic propagation properties and passive sonar detection performance in complex marine environments.Firstly,modeling theories were extensively investigated,including structural radiation noise,underwater acoustic channels,and passive sonar detection capabilities.Subsequently,these three aspects were integrated to establish a simulation process for evaluating the structural acoustic stealth of AUVs.Finally,the accuracy and effectiveness of the simulation process were verified through numerical examples,demonstrating the close cor-relation between AUV's acoustic stealth and these three factors.This simulation process can serve as a technical foundation for developing software for structural acoustic stealth analysis.
