Vital sign monitoring of a non-stationary human through IR-UWB radar

초록

In this paper the vital sign monitoring of a non-stationary human are measured by combining vital sign monitoring algorithm with movement detection method. First respiration and heart beat rate for a stationary human are explained and then a method for movement detection is discussed. The movement detection method is based on the autocorrelation property of a signal. Once the movement is detected then the most recent measurement value (before the movement is detected) is considered as the measurements throughout the motion period. And then the measurement process is restored when object comes back to stationary state. Experimental results are given to prove the stability of the algorithm.
