Range-gating technology for millimeter-wave radar remote gesture control in IoT applications

Touchless hand gesture using portable millimeter-wave radar sensors an enabling technology for Internet of Things (IoT) applications. In this paper, we investigate the feasibility of using a frequency modulated continuous wave (FMCW) radar with noise removal and range gating method to recognize human hand gesture for a user moving in the radar's field of view. These detected hand gestures will be applied to remote control of computers or smart TVs at a distance from 0.3 m to 1.2 m.
