摘要 利用位势理论将散射问题的外边界问题转化为第一类边界积分方程求解,再利用Backus-Gilbert方法给出了二维空间的数值结果,与Tikhonov正则化方法比较,虽然精度稍差一些,但是计算方法和计算机实现比较简单. A Backus-Gilbert method is presented to solve the time-harmonic acoustic wave scattering problem.Potential theory is used to transfer the exterior boundary value problem into the boundary integral equation of the first kind .Numerical result in two dimension is given compared with Tikhonov regularization method , this method has less accuracy, but compute is more simple.
