The inverse problem we consider in this survey is to determine the
shape of an obstacle from the knowledge of the far field pattern
for the scattering of timeharmonic waves. We will concentrate on
uniqueness issues, i.e., we will investigate under what conditions
an obstacle and its boundary condition can be identified from a
knowledge of its far field patterns for incident plane waves. We
will review some classical and some recent results and draw
attention to open problems.
