In this report I would like to introduce the uniqueness results and numerical methods for the inverse problems corresponding to the external scattering by  inhomogeneous media with unknown obstacles inside, multi-layer internal scattering problem and fluid-solid interaction scattering problem. The uniqueness theory of the inverse problem in the report is a novel mathematical theory, which can be applied to different kinds of scattering problems.
