摘要
针对散射声场的计算问题,将奇异积分处理技术应用于目标的低频声散射的数值计算、理论验模与仿真试验。结果表明,ka<3时,新方法的仿真结果与解析值以及等价面元近似方法取得了较好的一致;而ka 3时,新方法的仿真结果要好于等价面元近似方法。
Aiming at the question of computation of acoustic scattering, the paper applied the new method which is hansed on the technique of mathematical processing of singular integral into the calculation of acoustic scattering at low frequency. The results of simulation indicated that the new method is in good agreement with theoretical results and the results of equivalent facet method when ka〈3, but the new method is better than equivalent facet method while ka≥Y3.
