Micro-Doppler Features Analysis of the Wheeled Vehicle and the Tracked Vehicle

Micro-Doppler signature produced by micro-motion contains movement and structure information which is useful for radar classification and recognition. In order to recognize the wheeled vehicle and the tracked vehicle in ground battle, the motion dynamics and echo models of the scattering point on wheeled vehicle and tracked vehicle are set up respectively. Then the micro-Doppler features of them are quantitatively analyzed. Furthermore, the smoothed pseudo Winger-Ville distribution method is proposed for extracting micro-Doppler modulation. Finally, simulation results demonstrate the correctness of the theoretic analysis and the validity of the extraction method.
