RF and optical based photoplethysmography (PPG) have been recently developed for non-contact vital sign detection, due to their numerous advantages. In this paper, UWB radar, and camera-based monitoring are applied in vital sign detection and compared. In this paper, a mathematical signal model for the UWB Doppler radar, and another one for the camera ...
