Abstract:
Detection of human respiration and heartbeat is an essential demand in medical monitoring, healthcare vigilance, as well as in rescue activities. Radar is an important tool to detect human respiration and heartbeat. Compared to body-attached sensors, radar has the advantage of detection without contact to a subject, which is favorable in practical usage. We conducted preliminary studies on ultra-wideband (UWB) radar for detection of respiration and heartbeat by computer simulations in this paper. The main achievement of our work is the development of a UWB radar simulation system, which is designed in line with real implementation. Using the developed system, three UWB frequency bands are compared for respiration and heartbeat detection. The effects of using antenna arrays are also examined.
