Doppler radar for heartbeat rate and heart rate variability extraction

This paper presents a Doppler radar system used to detect the heartbeat signal from a d√istance of one meter. The proposed system is based on using a vector network analyzer and two antennas. Measurements are performed at 16 GHz for different power levels between 0 and •25 dBm. Both heartbeat rate and heart rate variability are extracted and compared to a simultaneous ECG signal.
