摘要
This paper considers the inverse scattering problem of an obstacle in R2 with impedance-type boundary. Our aim is to reconstruct the boundary impedance coefficient from the knowledge of scattered waves. For this ill-posed problem, we establish an effective inversion scheme to recover the unknown impedance in terms of the potential theory and optimal technique. Both convergence of the approximate solution and numerical example are presented.
