Detection of human targets using ultra-wide band through-the-wall radar

In this paper, an ultra-wide band (UWB) through-the-wall radar (TWR) prototype is described, and experiments are performed on detecting human targets behind wall. An adaptive background subtraction method is applied to signal processing to reduce clutter and antenna couplings. Range-time histories of an adult male person behind wall are presented for different locomotion states such as standing, marking time, and walking along cross-range direction.
