Continuous-wave radar at 4 GHz is a feasible technology for accurate and reliable non-contact monitoring of breathing and heartbeat.
Supports non-contact vital signs monitoring development; leaves open prospective validation before clinical adoption in cardiology.
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 of monitoring the vital signs activity in an accurate and reliable way.
