Hand gesture recognition (HGR) based on radar technology is becoming a hot topic recently. In this paper, we utilize a regular Wi-Fi transceiver chipset to construct a coherent radar sensor. The direct conversion and digital baseband signal processing technologies are used to detect hand motions with specific signatures. Experiments based on a dual-channel receiver aiming to detect two-dimensional motions are conducted, and the results show promising potentials in HGR applications.
