title: Feasibility of heart rate variability measurement from quadrature Doppler radar using arctangent demodulation with DC offset compensation.
abstract: This paper describes the experimental results of the beat-to-beat interval measurement from a quadrature Doppler radar system utilizing arctangent demodulation with DC offset compensation techniques. The comparison in SDNN and in RMSDD of both signals demonstrates the potential of using quadrature Doppler radar for HRV analysis.
