摘要：

Microwave Doppler radar has potential to provide a practical tool for noncontact detecting cardiopulmonary movement. In this paper, a noncontact sensor of vital signs was realized based on continuous wave Doppler radar, in addition, real-time signal processing was studied for single target noncontact cardiopulmonary monitoring, including short-time Fourier transform, Sinc interpolation and peak searching. These methods can improve the accuracy, response speed and shorten the latency of cardiopulmonary Doppler radar signal processing considerably, with relatively small amount of calculation.
