Abstract :
We present the development of a 228 GHz heterodyne radar system for the remote measurement of respiration and heart rates. The advantages of a millimeter wave system include a higher sensitivity to small displacements, transmission through the atmosphere and clothing and the ability to maintain a collimated beam over large distances. We present a set of respiration and heart rate measurements out to a range of 50 meters.
