Abstract
Methods and systems for estimating vital signs of vehicle occupants using Ultra-Wideband communication. UWB signals are transmitted from one UWB system node to another UWB system node. Channel impulse responses (CIRs) associated with the UWB signals are determined. Based on the CIRs, in some embodiments velocities associated with the UWB signals are determined, and activities of vehicle occupants are classified based on the CIRs along with vital signs such as breathing rates. In other embodiments, based on the CIRs, phase unwrapping of phase features associated with the CIRs is performed, and principle component analysis (PCA) transforms the CIRs, allowing estimated vital signs such as breathing rates to be determined.
