Abstract
When a human body is illuminated by an electromagnetic wave, the backscattered wave is modulated by the periodic body (thoracic) movements due to the heartbeat and breathing of the human target. With proper processing of this backscattered wave, it is possible to extract useful information about the heart and breathing signals that modulate it. The aim of this research work is the design and development of an X-band microwave life detection system for detecting humans trapped behind rubble or obstacles. The mobile microwave sensor that was constructed permits the detection of body movements due to breathing at a distance of 3–5 m (without any obstacle in between) and also at a distance of 2 m behind a concrete obstacle (a door or wall) of medium thickness.
