Abstract

In this paper we present the final results of a project devoted to show the abilities of Time Reversal processing for Through-The-Wall (TTW) detection of human targets. From a multistatic-multiview UWB radar system, experimental data from realistic TTW scenarios are collected and rearranged to form the multistatic data matrix K. The results of the singular value decomposition of the K matrix are used to build an efficient detector combining directions and arrival times. Images from different radar scenes (with canonic or human targets) are presented and discussed.
