摘要
提出一种方法,利用远场模式的完全数据与不完全数据反演声波阻尼区域,证明了方法的收敛性,并给出若干数值例子.
The inverse scattering problem we are considering in this paper is to determine the acoustic wave impedance boundary. A method is presented which use complete and incomplete data of the far field pattern of the scattering wave to recover the impedance boundary. The convergence of our method is proven. In addition, we give several numerical examples, these examples show the practicality of our method.
