In this paper, a sparsity-driven method of micro-Doppler analysis is proposed for dynamic hand gestures recognition with radar sensors. The sparse representation of the radar signals in the time-frequency domain is achieved through the Gabor dictionary, and then the micro-Doppler features are extracted by using the orthogonal matching pursuit (OMP) algorithm and fed into classifiers for dynamic hand gesture recognition. The proposed method is validated with real data measured with a K-banddoi:10.1109/radar.2017.7944336 fatcat:mdssqo2jf5alvenbi26jtwhbeu
