Single channel FMCW radar in moving scenario

Single channel frequency modulated continuous wave(FMCW) radar is attracting considerable critical attention in recent years due to its small size and low cost. However, the velocity-angle coupling problem occurs in a moving scenario, which eventually leads to obstacles for the application of beamforming. For this problem, the paper proposes a motion compensation method, and based on this method, a single channel FMCW radar signal processing flow is proposed. Numerical and experimental results are provided to validate the proposed method. It is suggested that the velocity-angle coupling problem can be effectively solved by the proposed motion compensation method, and moving targets can be effectively detected by using this single channel FMCW radar signal processing flow.
