【 摘 要 】

The through-the-wall inverse scattering problem is analyzed via the linear sampling method. The reciprocity gap formulation of the linear sampling method is used to reconstruct an object within a closed-off room. In order to apply this method, a numerical method to model a point source is needed, along with knowledge of how the numerical fundamental solution differs from the analytic one. Application of the linear sampling method to the Finite Difference Time Domain solution is described and illustrated, and results to reconstruct objects in the through-the-wall setting are shown.
