Abstract: Based on the Radon-Wigner transform (RWT), the Doppler resolution and extraction are studied for velocity and acceleration of maneuvering target. The pulse Doppler radar echo model of maneuvering target and the Fourier transformation processing method are offered. The RWT method is used to estimate the parameters of maneuvering targets. The Taylor analytical expression, the velocity and acceleration independent resolution expression and the joint resolution expression are proposed. It is indicated that the motion parameters can be distinguished if the path deviation between different maneuvering targets reaches one-half wavelength. The resolution capabilities of Fourier transform,Radon-ambiguity transform(RAT) and RWT method are simulated and compared. The simulation results show that RWT has the strong resolution capability of velocity and acceleration. The joint resolution condition of velocity and acceleration is validated.

Key words: information processing, pulse Doppler, Radon-Wigner transform, Radon-ambiguity transform, acceleration resolution, joint resolution of velocity and acceleration
