Abstract :
This paper presents a system for hearbeat detection using microwave Doppler technique. Using a vector network analyzer, a microwave system is tested for the detection of the heartbeat signal at a distance of 1 feet from a person. The proposed system shows the ability of detecting the heartbeat signals with the possibility of tuning the radiated power. Measurements are performed at 10dbm, 0dbm, -10dbm, -15dbm and -25dbm. Based on measurements perform for respiration and heart beatings, a signal representing the cardiopulmonary activity is presented. The heartbeat rate and heart rate are extracted from the signal using wavelet and classic filters.
