This study presents wireless vital signal tracking results of multi-carrier micro-Doppler radar installed in driver's seatback, which can be used to develop new e-healthcare services of smart cars in the future. The multi-carrier micro-Doppler radar utilize multiple frequencies to measure driver's vital signal in order to overcome the measurement deterioration by unwanted radar and radar movement. The method is briefly described in this paper. To evaluate the performance of the method for the driver's vital signal tracking, we installed the radar into driver's seatback in an automobile. In some scenarios, driver's heartbeat and respiration rate are measured in the automobile. We present the experiment setup and results for four volunteers' measurement data. The results show that the heartbeat rate tracking performance of the driver's seatback radar is better than the respiration tracking.
