Abstract
In through-the-wall radar imaging (TWRI), the presence of multipath create ghost targets which can adversely affect the image reconstruction process. Unlike genuine targets, ghost positions are aspect dependent which means their position changes with the transceiver location. This paper proposes efficient ghost suppression method exploiting aspect dependence feature with compressive sensing. The signal model is generalized so that the effect of front wall reflection and target-to-target interactions are accommodated. The method does not require the knowledge of the reflecting geometry which makes the scheme more practical. Results show that the proposed methods can greatly suppress multipath ghosts and thus increases signal-to-clutter ratio.
