A Robust Algorithm of Doppler Parameters Estimation for Airborne Radar
一种稳健的机载雷达杂波多普勒参数估计方法

Based on the Doppler Distributed Clutter(DDC) model,this paper studies the distribution of eigenvalues of the clutter covariance matrix and proposes a robust algorithm of Doppler parameters estimation for airborne radar.Compared with existing methods,the proposed algorithm has comparable performance for Doppler centroid estimation and shows superiority for Doppler spread estimation.The proposed algorithm is competent for most practical applications of airborne radar such as moving target detection(MTD) using Pulse-Doppler(PD) radar,especially for few sampling case.Numerical simulations prove the effectiveness of the proposed algorithm.
