—Intelligent driver assistance systems have become important in the automotive industry. One key element of such systems is a smart user interface that tracks and recognizes drivers’ hand gestures. Hand gesture sensing using traditional computer vision techniques is challenging because of wide vari-

ations in lighting conditions, e.g. inside a car. A short-range radar device can provide additional information, including the

location and instantaneous radial velocity of moving objects. We

describe a novel end-to-end (hardware, interface, and software)

short-range FMCW radar-based system designed to effectively

sense dynamic hand gestures. We provide an effective method

for selecting the parameters of the FMCW waveform and for

jointly calibrating the radar system with a depth sensor. Finally,

we demonstrate that our system guarantees reliable and robust

performance.
