Unobtrusive human activity classification based on combined time‐range and time‐frequency domain signatures using ultrawideband radar
Abstract In this proposed approach to unobtrusive human activity classification, a two‐stage machine learning–based algorithm was applied to backscattered ultrawideband radar signals. First, a preprocessing step was applied for noise and clutter suppression. Then, feature extraction and a combinatio...
