Comparison study of two approaches for bioradar data processing

In this paper, we present a feasibility study for life signs detection using a continuous wave radar working in the band around 4 GHz. The data processing is carried out by using two different data processing approaches, which are compared about the possibility to characterize the frequency behaviour of the breathing and heartbeat activity. The two approaches are used with the main aim to show the possibility to monitor the vital signs activity in an accurate and reliable way.
