Abstract :
A detailed modeling and analysis for the effect of the RF system on the human vital-signal estimation by a 60-GHz millimeter-wave Doppler radar has been developed. The simulation scheme uses the root-MUSIC algorithm to calculate the frequency error ratios of the estimated heartbeat and breathing signals by the radar detection system. From the simulation results, it is found that root-MUSIC method is robust to analyze the effects of phase noise on the frequency estimation of the detected heartbeat and breathing signals. The simulation result will be very useful for the RF system design specifications for the millimeter-wave Doppler radar.
