An Experimental Study Of 2-D Cardiac Motion Pattern Based On Contact Radar Measurement

This paper presents an experimental study of human cardiac motion pattern detection using Doppler radar. The measurement results show that with contact radar detection, more motion information can be detected compared with the remote detection. Besides, measurements at three chest positions confirm that cardiac motion pattern has 2-D variance on the chest plane. These detection experiments indicate that lots of valuable cardiac motion information would be lost if we only measure it remotely or treat it as a simple I-D back and forward motion.
