    Aspect Dependent Multipath Ghost Suppression in TWRI Under Compressive Sensing Framework
    (2015) Abdalla, Abdi T; Muqaibel, Ali H.; Al-Dharrab, Suhail
    In through-the-wall radar imaging, multipath propagation can create ghost targets which can adversely affect the image reconstruction process. The fact that the ghost positions changes with the radar locations which is referred to as aspect dependence has been reported as among the features distinguishing ghost from true target. This paper proposes ghost suppression method which exploit the aspect dependence feature under compressive sensing framework. The existing signal model is modified so that the location of reflecting geometry is no longer a constraint. Also the sensing matrix is greatly reduced making the methods more attractive. Simulation results demonstrate the effectiveness of the proposed methods.
