In this paper, we present a low cost ultra wideband (UWB) biometric radar sensor for respiration detection and monitoring applications. By using pulse Doppler radar technology, the developed sensor goes beyond detecting the breathing of a single person as conventional radars do; to simultaneously localizing and monitoring multiple human objects as well. The biometric sensor achieves a high range resolution of 3 mm, which makes it capable of detecting very tiny motions, such as breathing and heartbeat. A high unambiguous Doppler velocity of 9 m/s is obtained by the sensor and makes it an attractive device to monitor and investigate any other human physical activities too. Experiments of detecting the location and respiration characteristic of single and multiple human objects will be discussed. [ABSTRACT FROM PUBLISHER] |
