Assessment of Linear Sampling Method and Factorization Method for Through the Wall Imaging

In this study, we considered a through wall imaging scenario with microwaves. The scattered field is calculated via Method of Moment and background is estimated by mean electrical properties of the wall. In order to reconstruct targets in investigated domain, two qualitative imaging methods, namely linear sampling method and factorization method are applied. These methods are applied and compared with respect to various criteria such as selection of regularization parameters, selection operating frequency, thickness of the wall and conductivity of the wall.
