Detection and tracking of moving or trapped people hidden by obstacles using ultra-wideband pseudo-noise radar

Efficient detection of people hidden by walls or rubble is of interest for rescue, surveillance and security operations. A useful method applies an ultra-wideband radar approach for this purpose since electromagnetic waves in the lower GHz-range penetrate most non-metallic materials. The paper gives a short overview of the particular radar conception and shows some experimental results for the tracking of people, detection of breathing people and reconstruction of room interiors.
