Abstract	For synthetic aperture imaging of through-wall-radar, the multi-path propagation between target and walls introduces the ghosts into the formed image. This paper proposes a new algorithm for suppressing these multi-path ghosts. A multi-path model in an enclosed building is first developed. By analyzing the model, we obtain an important feature of the multi-path ghosts to be defined as aspect dependence. Then, based on the aspect dependence, we introduce the sub-aperture imaging to suppress the ghosts. Simulation results show that the proposed method reduce the ghosts as well as increase the signal-to-clutter ratio of image.
