Abstract :
Cardiopulmonary signals can be detected at a distance using simple Doppler radars operating in CW mode. Tests with and without audio modulation show the feasibility of measurements with this hardware, providing a maximum measured difference to the reference of just 1.6 bpm for heart rate. Tests show good correspondence of heart/respiration rate with the reference data.
