First, today's RF chips are more efficient and smaller than comparable chips of a few years ago. Second, the high demand for new sensor systems in health-care, automotive, and industrial applications, especially as the field of smart factories emerges, has boosted development of ultralow-cost radar modules for the mass market [3], [4].en1527-3342201919197Journal Article10.1109/MMM.2018.2875612Other
