TOA association for handheld UWB radar

Handheld ultra-wideband radars can be used with advantage during rescue, surveillance or security operations by reason that they enable to track targets moving behind walls. The radar signal processing for that purpose represents a complex process with several processing phases. In this paper, the attention is devoted to the estimation of the correct input data for the localization phase. This is done by applying a new approach that combines the time of arrival (TOA) estimation and the data-association into a single step. The performance of the proposed algorithm is illustrated by processing of real radar signals. Here, the obtained results confirm that the proposed algorithm can provide good, stable and robust TOA estimation including deghosting task solution.
