Web7 mai 2012 · A multipath model for sensing through walls using radars is derived, which improves the radar system performance by aiding in ameliorating the false positives in the original SAR image, as well as increasing the signal-to-clutter ratio at the target locations, culminating in enhanced behind the wall target detection and localization. 145 PDF

WebRadar is an attractive sensing modality for this purpose due to its all-weather day or night operation and the potential for a high area coverage rate. However, radar is not achieving the goal of persistent urban surveillance for several reasons. WebFor simplicity, we consider the multipath geometry from the radar to the target; this can be symmetrically extended from the target to the radar.
