Abstract
In recent years ultra-wideband (UWB) radios have found increasing use in applications requiring precise ranging and localization of active tags, in part due to the inherent bandwidth and thereby accuracy in range determination [1–4]. For the same reason, UWB is a suitable technology for sensing. Radar-based sensors offer a compelling modality in scenarios such as user presence detection and vital signs monitoring [5, 6].
