Abstract:
During the last decade, the development of impulse radio ultra-wideband (IR-UWB) radar sensors have led them to be considered as a viable substitute of polysomnography (PSG), the gold standard, in the acquisition of the primary vital signs of the human body, during sleep. In this work, we investigate whether radar sensor recordings of the chest and heart displacement can accurately substitute the PSG chest and heartbeat signal measurements. We develop an innovative pipeline of handling the radar-based recordings, which includes: motion detection, extraction of the respiration, heartbeat and activity vital signs and estimation of the respiratory and heartbeat rates (RR and HR, respectively). Next, we apply our proposed methodology to data from 28 subjects gathered during their sleep. Results show that the radar sensor's measurements can be comparative to those produced by the PSG. Specifically, the RR and HR frequencies, of the radar and the PSG, have average Pearson's correlation, greater than 0.9 and 0.8, respectively.
