- W4319586656 abstract "Hand and finger gesture sensing with millimeter wave (MMW) radar is an emerging technology. In this paper, we propose a novel linear frequency modulation and multiple frequency shift key (LFM-MFSK) combined waveform to sense the finger gesture and a new 1D searching phase unwrapping algorithm for the unambiguous range estimation of the significant scatterers on the hand of interest. By utilizing the new waveform, the hand is resolved from other objects in the range domain, and the different fingers can be resolved in the Doppler domain with high Doppler resolution. Besides, the unambiguous high accurate range estimation of the fingers can be obtained from the phase differences of the returns via a 1D searching phase unwrapping algorithm based on the Chinese remainder theorem (CRT). The 120GHz millimeter wave radar with the LFM-MFSK waveform is designed, and the proposed method is verified with the returns of two common finger gestures." @default.
