Abstract

For remote vital signs and occupancy detection in many smart home/building applications, radar sensors are a preferred option over cameras, due to privacy preservation and robustness to ambient light conditions. These radars not only need to provide precise range and vital signs information over meters distance, but also preferably can operate on a battery up to a few months or even years, for cost and practical reasons (like smoke detectors). State-of-the-art remote vital-sign sensors typically use an impulse-radio UWB (IR-UWB) radar [1,2] because it provides a range resolution <20 cm. However, their power consumption is typically in the order of 100's of mW, preventing long-term maintenance-free battery-powered operations. Although mains power can be used to supply such radars, this is not always available, depending on the location and the building type, and the installation cost (e.g., power routing) is significantly higher than for battery-powered ones. In this work, a burst-chirp radar with an energy-efficient chirp generation is proposed, leading to a record-low power consumption of 680 μW.
