Development of a Remote Vital Signs Sensor

This paper describes the work at Sandia National Laboratory to develop sensors that remoteley detect uniqe lifeform characteristic, such as breathing patterns or heartbeat patterns. this paper have be used to assess someone's malevolent intent. the basic concept od the operations for the project, system developement issues, and the preliminary results for a radar device currently in-house technology currently being evaluated is reviewedm as well as ideas for other potential technologies to explore. a radar unit for breathing and heartbeat detection is being tested, and the applicability of infrared technology is bein explored. the desire for rapid prototyping is drivng the need for off-the-shelf technology. As a conclusion, current status and future directions of the effort are reviewed
