The study on detection of the life signals of human subject based on Micropower UWB radar

The definition, principle, characteristics of micropower Ultra-Wide-Band (UWB) radar are described and discussed in this paper. The human subject is experimented using the UWB radar developed by our team. The experimental results show that UWB radar is able to detect the life signals of the human subject such as respiration and heartbeat without any sensor and electrode touching the subject.The radar can be applied to non-invasive detection of life signals.
