Configuration of Multisensor CW Radar for Hand Gesture Detection

Abstract

Radar has many implementations in everyday life in various fields such as the military, health and many more. Radar has also been developed so that it could be combined with other technologies. For example, the human to machine interface (HMI). HMI has the ability to translate cues from the user so that it could be understood by the machine. Based on their respective capabilities, radar and HMI then combined so that they could get new capabilities based on their respective functions. One type of radar that is known is the continuous wave (CW) radar. CW radar is generally used to detect objects based on the Doppler effect. Then CW radar combined with HMI. The results obtained by using a multi-sensor configuration, namely horizontal and vertical configurations could detect hand movements. The horizontal and vertical configurations could both detect with an accuracy rate of 87.5 % of the test in each configuration with a distance of 20 cm in terms of power and measurement accuracy. So, it could be concluded that using a multi-sensor configuration in the form of horizontal and vertical could detect hand gesture movements.
