提出了零陷展宽对角载入算法，该算法既解决了干扰在快速运动时，干扰零陷过窄的问题，又解决了协方差矩阵误差和导向矢量误差存在时，算法稳定性变差的问题。同时，通过对角载入因子和采样协方差矩阵间的关系确定了对角载入算法载入因子的值。计算机仿真结果表明该算法有很好的稳健性，以及较宽的零陷。

The null broadening and diagonal loading algorithm is proposed,which not only addresses the problem of narrow nulls as the interference in the fast movement condition,but also solves the problem of the bad algorithm stability as the error covariance matrix and steering vector errors existing. Meanwhile,diagonal loading factor values of the algorithm are determined based on the relationship between sample covariance matrix and diagonal loading factor. The computer simulation results show that the algorithm has good robustness,as well as broadening nulls.
