Heart and respiration rate measurement using Doppler radar is a non-contactand non-obstructive way for remote thorough-clothing monitoring of vital signs.The modulated back-scattered radar signal in the presence of high noise andinterference is non-stationary with hidden periodicities, which cannot bedetected by ordinary Fourier analysis. In this paper we propose acyclostationary approach for such signals and show that by using non-lineartransformation and then Fourier analysis of the radar signal, the hiddenperiodicities can be accurately obtained. Numerical results show that the vitalsigns can be extracted as cyclic frequencies, independent of SNR and withoutany filtering or phase unwrapping.
