International audience. This paper presents different signal processing techniques used in separating cardiopulmonary signals measured using a microwave Doppler radar. For different sides from the person under test, the microwave system is tested for several operational frequencies simultaneously with a PC-based electrocardiograph. Wavelet transforms are used in order to separate heartbeat signal from the cardiopulmonary signals. High accuracy is obtained in terms of heartbeat rate for the whole measurements.
