Directional multipath exploitation for urban target localization with a single-antenna

In this paper, we propose a new multipath exploitation approach for urban target localization with a single radar unit. The proposed approach utilizes the embedded directivity in ultra wideband (UWB) antennas to estimate target positions using interior wall multipath returns. We assume resolvability of the multipath components, which is made possible by virtue of using UWB radar signals. This approach is most attractive when only few multipath returns are detectable due to propagation obstructions or owing to their corresponding low signal-to-noise ratios. Supporting simulations results are provided.
