摘要：This paper presents a Doppler radar system used to detect the heartbeat signal from a distance of one meter. Theproposed system is based on using a ultrasonic transceiver and two antennas. Measurements are performed at 2 GHz fordifferent power levels between 0 and -25 dBm. Both heartbeat rate and heart rate variability are extracted and compared toa simultaneous ECG signal.
