摘要:
传统JDL算法严格要求空时二维导引矢量间是相互正交的.对传统JDL方法进行改进,突破了要求该算法中变换必须是正交变换的规定,用一种非正交变换构建了性能更好的JDL算法,而原JDL则仅是本算法中的一种特殊情况.然后使用Krylov子空间空时自适应处理算法进行降秩处理,不需要对协方差矩阵进行估计,也不需要对样本协方差矩阵进行求逆,使得算法的处理速度得到加快.用仿真数据以及实测数据验证了所提出的非正交JDL方法性能的改善效果.
Abstract:
Space-time 2D steering vectors are required to be orthogonal in traditional JDL algorithm. An improved JDL algorithm is proposed which changes the rule that the transformation must be orthogonal transformation. The better JDL using nonorthogonal transformation is achieved traditional JDL as only a special case of the new algorithm. Then rank-reduced STAP is employed in Krylov subspace without the estimation and the inverse of the covariance matrix to obtain faster speed. Finally, the simulated results confirm the efficiency of the new algorithm shown in this paper.
