In this talk, an inverse scattering problem with impedance boundary condition are considered. For such a problem, it is required to reconstruct the shape of scatterer and the boundary impedance simultaneously. But in some cases, the shape of obstacle is known in advance, and hence we only need to recovery the boundary impedance from a knowledge of the far-field patterns. The uniqueness, stability and numerical schemes for reconstructing the impedance are reviewed with some comparisons.
