Abstract :
This study presents a 14 GHz CW Doppler radar to measure respiration and heart rate. A leakage cancellation technique is used to detect the heart rate of humans for long range detection. Arctangent demodulation without dc offset compensation can be applied because of the heterodyne receiver structure and the leakage cancellation technique. HRV analysis of the radar system and the ECG signal, which is measured directly, are compared. Based on the measurement results, the radar can detect respiration and the heart rate with a small error rate.
