In partnership with the National Aeronautics and Space Admin-istration’s (NASA) Jet Propulsion Laboratory, the DHS Science and Technology Directorate (S&T) is developing a technology called Finding Individuals for Disaster and Emergency Response (FINDER). FINDER uses low-power microwave radar to detect the small movements from breathing and the heartbeat of a buried victim, even when the signal must pass through several feet of rubble and building debris. FINDER searches for the unique characteristics of human breathing and heartbeat to distinguish between humans, animals, and mechanical movement. It can also distinguish between multiple victims, since each person’s breathing and heartbeat patterns are different.
