声场计算中奇异积分处理的新方法

摘要

为了利用物理声学方法计算任意目标的散射声场,基于VIJAYAKUMAR等人提出的求解奇异积分的方法提出了一种有效解决水声问题中的奇异积分的新方法,并利用MATLAB编程进行了仿真计算,得到了标准刚性球前向散射声场的回声,并将全局法运用到了非齐次方程中,仿真结果表明,该方法计算精度较高,计算速度满足工程需要.%In order to compute accoustic scattering of objects with aribitrary shape by Helmholtz-Kirchhoff Method,this paper introduced the golbal approach with high efficiency and simulate this approach bu MATLAB, then get forwardscattering results, simulation also indicate this method can get high efficiency and high speed in nonhomogeneous formulations.
