Abstract
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. © 2011 Wiley Periodicals, Inc.
