文摘Consider an inverse scattering problem for a scatterer D R3 with impedance type boundarycondition. By defining the scatterer shape in a completely new way, we give a constructive method to recoverthe scatterer shape with unknown impedance coefficient. The uniqueness for this inverse problem is also obtained.
