Abstract :
In this paper, a Doppler radar system for cardiopulmonary detection will be described. The idea of our design is to use inexpensively commercially available motion sensor detectors. So a quadrature receiver board from AD-8347 is used. Experiment results indicate that this system can extract respiration and heartbeat rates at a short distance with digital signal processor.
