Doppler parameter estimation of airborne radar based on a novel clutter model

To characterize the Doppler spectrum center shift and width spread of airborne radar clutter, a novel Doppler distributed clutter model is established in this paper. Based on this model, many parametric methods are also proposed to estimate Doppler parameters in the temporal domain and more excellent performance is achieved than conventional frequency domain methods. Both simulation and real experimental results are also provided to show the validity of the new clutter model and new approaches.
