Radar for vital signs characterization: A comparison between two different frequency band systems

This paper deals with the exploitation of two bio-radar systems (4 GHz and 14 GHZ frequency) developed at Remote Sensing Laboratory of the Bauman Moscow State Technical University for vital signs characterization (breathing and heartbeat). In particular, an experiment has been performed with the two radar systems, in order to appraise the different performance, in terms of detection and accuracy, with respect to vital signs estimation. For this experiment, the data have been processed by means of a recently developed approach that allows us to perform the parameter estimation (and therefore the overall monitoring process) in an automatic way.
