Microwave system for the detection of trapped human beings

When a human body is illuminated by an electromagnetic wave, the backscattered wave is modulated by the periodical body (thoracic) movements due to heartbeat and breathing of the human target. With proper processing of this backscattered wave, it is possible to extract useful information for the heart and breathing signals that modulate it. The aim of this research project is the design and development of an X-band microwave life detection system for detecting humans trapped behind rubble or obstacles.
