【摘要】 针对水下复杂目标高频收发分置散射声场特性研究过程中,传统边界元法存在计算效率低,稳定性差等缺陷,本文通过高频压力声学法与边界元法对水下简单目标收发分置的声目标强度进行对比计算,并基于高频压力声学法具体讨论了BeTSSi潜艇模型高频收发分置散射声场特性,数值计算结果表明,当波长远小于水下目标尺寸时,高频压力声学法分析速度快,并且计算结果与边界元法结果相比得到了很好的近似,采用高频压力声学法研究水下复杂目标高频收发分置散射声场特性是可行的。更多还原

【Abstract】 In the process of studying the high-frequency transceiving scattering sound field characteristics of underwater complex targets, the traditional boundary element method has the defects of low computational efficiency and poor stability.In this paper, the high-frequency pressure acoustic method and the boundary element method are used to compare the acoustic target strength of the underwater simple target. Based on the high-frequency pressure acoustic method, the high-frequency transceiving scattering sound field characteristics of the BeTSSi submarine model are discussed in detail. The numerical results show that when the wavelength is much smaller than the size of the underwater target, the high-frequency pressure acoustic method is fast and the results are well approximated. It is feasible to study the characteristics of high-frequency transceiving scattered sound field of underwater complex targets by high-frequency pressure acoustic method.更多还原
