PhD student Jee-Hoon Lee (advisor : Seong-Ook Park) received BEST STUDENT PAPER AWARD from 2013 international symposium on antennas and propagation (isap 2013) on October 23 ~ 25 2013 with paper titled “A 14 ghz non-contact radar system for long range heart rate detection”
This research presents a 14 GHz CW Doppler radar to measure respiration and heart rate. A leakage cancellation technique is used to detect heart rate of human for long range detection. Arctangent demodulation without the 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 the respiration and heart rate with a small error rate.
