A new method for vital sign monitoring using IR-UWB radar

Abstract

Quadrature Demodulation IR-UWB radar is a new form of impulse-radio Ultrawide Band (IR-UWB) radar and it can improve the resolution of distance measurement. This paper focuses on a new method for vital sign - specifically breathing rate and heart rate - from the phase of recorded I/Q signals, using Quadrature Demodulation IR-UWB radar. The results of the experiment show that a better estimation of heart rate can be got from such a new method based on the phase difference.
