摘要
提出了一种方法,利用正则化方法和积分方程,由散射波的近场数据反演时间调和声波阻尼系数.给出了该方法收敛性的证明及数值例子,算法与数值例子表明这种方法不仅简单而且很有效.
The inverse time-hormonic acoustic wave scattering problem we are considering here is to recover the impedance coefficient from the near field data of the scattered wave. A method is presented and the convergence of this method is proven. Numerical examples are given. They show that the method is both accourate and simple to use.
