In the paper, we present the results of research, design and test of device for non-contact measurement of heart and respiration rates. The device based on the 24 GHz frequency Doppler Radar and has high precision, non-invasive, convenient and safe for users. The analysis and comparison results of measured heart and breathing rates by using Radar Doppler and traditional contact method have showed that two measurement methods give almost similar results: the deviations in measured heart and breathing rates by two methods were 1.87 and 0.55 beat per minute, respectively.
