Modeling of human torso time-space characteristics for respiratory effective RCS measurements with Doppler radar

Summary form only given, as follows. This paper demonstrates a theoretical model for the torso time-space characteristics by formulating the baseband signal of a CW Doppler radar system as a superposition of two components, one from the thorax and the other from the abdomen. Measurements of a female subject in a supine position are used for verification. By reproducing the measured baseband signal, the respiration parameters could be identified for the subject under test.
