Key result
Noncontact heart rate monitoring using Doppler radar and continuous wavelet transform provided very accurate and robust performance up to 1 meter, but accuracy decreased at 2 meters.
Why the study?
Does Doppler radar with continuous wavelet transform accurately detect heart rate?
Does Doppler radar with continuous wavelet transform accurately detect heart rate?
Doppler radar combined with continuous wavelet transform can accurately monitor heart rate without contact up to a distance of 1 meter.
Supports noncontact HR monitoring feasibility to 1 m; leaves open clinical validation and distance optimization.
An algorithm based on wavelet transform is utilized in detecting and examining the heartbeat signal obtained from a Doppler radar.Time–frequency localization properties of wavelet transform were used to examine the signal and provided detail of swift and slow changes in heart rate over very small periods resulting in better determination of the accuracy of the Doppler radar. Till 1 m, a very accurate and robust performance was observed for the Doppler radar. Even at 2‐m heart rate was detectable but not with reasonable accuracy.
