Abstract

This paper proposes a gesture recognition method based on frequency modulated continuous wave radar. The radar echo signal reflected when the hand moves is analyzed and processed in the time and frequency domain to extract the multidimensional parameters such as Doppler, range, and horizontal angle of the gesture. These parameters are spliced into a Range-Doppler-Time-Map and Range-Horizontal-Angle-Time-Map according to a fixed frame length to form a data set containing six kinds of gestures. Finally, a shallow convolutional neural network with only 5 layers is used to recognize and classify six gestures. The experimental results show that, compared with the traditional single parameter features such as Range-Time features and Doppler-Time features, the combined features of Range-Doppler-Time and Range-HorizontalTime can more accurately deal with the six gestures.
