摘要
使用边界积分方程方法与正则化方法求解多体障碍散射问题,使用优化方法求解多体障碍反散射问题.由于引入辅助障碍物,因此散射信息更丰富,重构效果更好.数值实验表明,所给方法优于经典的优化方法.
The multiple scattering problem was solved by means of a boundary integral equation method and regularization method, the inverse problem was solved by virtue of optimization method. The introduction of auxiliary obstacle makes scattering information richer and reconstruction better. Numerical results show the advantages of the method.
