摘要
针对声学亮点模型在仿真敷设声学材料的水下目标回波误差问题,采用有限元分析软件Comsol对二维敷设不同材料下的潜艇舱室结构模型进行数值仿真,并构建了基于不同材质仿真结果的目标强度数据库,供亮点模型直接调用。该项仿真在一定程度上提高了在不同表面材质上模拟目标回波仿真信号的能力,加强了仿真信号的逼真度,对工程应用具有借鉴意义。
Aimed at the error problem of the acoustic bright spot model in echo simulation of the underwater targets laying the acoustic materials,and using the finite element analysis software Comsol,numerical simulation is carried out for the structural model of the submarine cabin laying two-dimensional different materials.A target intensity database based on the simulation results of different materials is constructed to be directly called by the bright spot model.To a certain extent,the simulation can improve the signal simulation ability on the targets laying the different surface materials,and enhance the fidelity of simulation signal.It has reference significance for engineering applications.
