Popis: We consider the inverse scattering problem of determining the shape of a cavity with impedance boundary condition from sources and measurements placed on a curve inside the cavity. It is shown that both the shape $\partial D$ of the cavity and the surface impedance ? are uniquely determined by the measured data and numerical methods are given for determining both $\partial D$ and ? where neither one is known a priori. Numerical examples are given showing the viability of our method.
