A novel detection and parameter estimation method for air maneuvering target based on reconstruction time sample and Wigner-Ville Distributed (WVD) is proposed in this paper. Firstly, reconstruct time sampling method is applied to reconstruct the signal by using the space samples, which is equivalent to increasing the number of time samples within a Coherent Processing Interval (CPI). Then WVD method is utilized for reconstructing signals to achieve parameter estimation. The proposed method can achieve the detection and parameter estimation of the maneuvering target effectively without the need of precisely known of azimuth of target when the data sample is limited. The simulation result is provided to demonstrate the effectiveness of the proposed method.
