Feasibility of HRV measurement from single-channel doppler radar

The single-channel Doppler radar system was evaluated for heart rate variability (HRV) measurement. Pearson PMCC, scatter plots, absolute differences, and mean were used and demonstrated good correlation between Doppler radar operating at different power levels and the finger pulse reference. Doppler radar may be of interest for heartbeat monitoring because of its remote sensing ability and shows good potential for HRV measurement.
