| Abstract: | 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. |
