Abstract :
Cardiopulmonary motion can be detected from a distance using radar. Which frequencies that are best suited for detecting heartbeats or respiration is connected to the radar cross section (RCS) of the physiological motion. In this paper, we investigate the RCS of human heartbeats and respiration in the frequency range 500MHz to 3GHz through calibrated radar recordings of two persons.
