RF-Protect

Abstract

In the last decade, both academia and industry have relied on FMCWradar based radio-frequency (RF) sensors to enable through-wall human tracking. These sensors capture reflections from human bodies to track occupancy of rooms [1], motion patterns of occupants [1,2], their daily activities [3], and their health metrics [4, 5]. Recently, Google has incorporated high frequency FMCW-based sensing into their smart home devices [6, 7], and Amazon received an FCC waiver [8] to conduct testing for the same.
