Short range imaging and localization of human body behind obstructing surfaces using UWB signals

This paper investigates the feasibility of three image reconstruction algorithms for Ultra Wideband (UWB) signals in applications of detection and localization of human targets behind obstructing surfaces. The image reconstruction algorithms are represented by unfocused SAR (Synthetic Aperture Radar), focused SAR and Radon transform based tomographic method. Due to the focusing effect obtained by applying a quadratic phase correction, the best performance is obtained if the measured signals are processed using the focused SAR algorithm.
