Target localization in urban sensing can benefit from angle dependency of the pulse shape at a radar receiver antenna.We propose\na localization approach that utilizes the embedded directivity in ultra-wideband (UWB) antennas to estimate target positions. A\nsingle radar unit sensing operation of indoor targets surrounded by interior walls is considered, where interior wall multipaths are\nexploited to provide target cross-range. This exploitation assumes resolvability of the multipath components,which is made possible\nby the virtue of using UWB radar signals.The proposed approach is most attractive when only few multipaths are detectable due\nto propagation obstructions or owing to low signal-to-noise ratios. Both simulated and experimental data are used to demonstrate\nthe effectiveness of the proposed approach.
