This paper studies the use of continuous wave (CW) radar for non-invasive estimation of vital signs, in particular respiratory and heart rate. We derive a realistic reference model for a stationary human subject. We propose methods for estimating the vital signs, including nonlinear and linear signal demodulation, as well as time-frequency methods utilizing the micro-Doppler structure of the signal. We show that real-world measurements with 24 GHz CW-radar taken from different positions close… CONTINUE READING
