Estimation of Motion Parameters of Moving Target using Wigner Distribution

The purpose of this paper is to estimate unknown motion parameters, acceleration and initial velocity, from the radar signal corrupted by random noise. The principal attack of the approach is to use the (pseudo)-Wigner distribution which is computed from the noisy observation data. Parameters are estimated by least-squares method for the noisy instantaneous frequency of returned signal. Numerical simulations are presented to verify the efficacy of the proposed method.
