本文采用两部多普勒雷达分别监测心脏和小腿的脉搏运动，实现脉搏波传导速度的无线测量。仿真和实验都证明了所提出的非接触PWV监测的可行性。一个三阶段的校准程序，包括直流偏移校准，电路延迟校准和天线辐射方向图校准，已经开发了可靠的长期PWV监测。用脉冲传感器进行线接触测量，验证了测量结果。
In this paper, two Doppler radars are used to monitor the pulse movements at the heart and the calf in order to measure the pulse wave velocity (PWV) wirelessly. Both simulation and experiment have been performed to demonstrate the feasibility of the proposed noncontact PWV monitoring. A three-stage calibration procedure, including DC offset calibration, circuit delay calibration and antenna radiation pattern calibration, has been developed for reliable long-term PWV monitoring. The measurement results have been verified by wired contact measurement with pulse transducers.
