ROBUST STAP METHOD BASED ON ARRAY MANIFOLD PRIORI KNOWLEDGE HAVING MEASUREMENT ERROR
(FR)
PROCÉDÉ STAP ROBUSTE BASÉ SUR UNE CONNAISSANCE A PRIORI DE VARIÉTÉ D'ANTENNE COMPORTANT UNE ERREUR DE MESURE
(ZH)
一种基于存在测量误差的阵列流形先验知识的稳健STAP方法
Abstract:
(EN)
A robust STAP method based on array manifold priori knowledge having measurement error comprises the steps of: S1, obtaining a clutter space-time steering vector set according to a given error range; S2, searching for an important space-time steering vector in the clutter space-time steering vector set, and calculating an eigenvalue and an eigenvector of the important space-time steering vector; and S3, obtaining a clutter covariance matrix according to the eigenvalue and the eigenvector of the important space-time steering vector, and obtaining a filter weight vector according to the clutter covariance matrix. Errors unavoidably exist in obtaining array manifold knowledge, which directly causes processing performance limitation of STAP based on the array manifold knowledge. Compared with the STAP method based on array manifold knowledge in the prior art, the method reduces requirements for the accuracy of priori knowledge, has a robust characteristic for the priori knowledge having certain errors, and can avoid a process of clutter covariance matrix inversion in designing a filter, thereby achieving the objective of reducing the computation complexity of a system.
(FR)
Un procédé STAP robuste basé sur une connaissance a priori de variété d'antenne comportant une erreur de mesure comprend les étapes consistant à : S1, obtenir un ensemble de vecteurs de direction espace-temps de fouillis selon une plage d'erreur donnée; S2, rechercher un vecteur de direction espace-temps important dans l'ensemble de vecteurs de direction espace-temps de fouillis, et calculer une valeur propre et un vecteur propre du vecteur de direction espace-temps important; et S3, obtenir une matrice de covariance de fouillis selon la valeur propre et le vecteur propre du vecteur de direction espace-temps important, et obtenir un vecteur de poids de filtre selon la matrice de covariance de fouillis. Il y a inévitablement des erreurs dans l'obtention d'une connaissance de variété d'antenne, ce qui provoque directement une limitation de performance de traitement de STAP sur la base de la connaissance de variété d'antenne. Par comparaison avec le procédé STAP basé sur la connaissance de variété d'antenne de l'état de la technique, le procédé réduit les exigences de précision de connaissance a priori, présente une caractéristique robuste de la connaissance a priori comportant certaines erreurs, et peut éviter un processus d'inversion de matrice de covariance de fouillis dans la conception d'un filtre, ce qui permet d'atteindre l'objectif de réduction de la complexité de calcul d'un système.

一种基于存在测量误差的阵列流形先验知识的稳健STAP方法,包括步骤:S1:根据给定误差范围下获得杂波空时导向矢量集;S2:在杂波空时导向矢量集中寻找重要的空时导向矢量,并计算重要的空时导向矢量的特征值和特征向量;S3:根据重要的空时导向矢量的特征值和特征向量获得杂波协方差矩阵,并根据杂波协方差矩阵获得滤波器权矢量。因阵列流形知识的获取中不可避免的存在误差,将直接导致基于阵列流形知识的STAP的处理性能受限。与现有的基于阵列流形知识的STAP方法相比,降低了对先验知识准确性的要求,对一定误差的先验知识具有稳健的特性,同时在设计滤波器过程中避开杂波协方差矩阵求逆的过程,从而达到了降低系统计算复杂度的目的。
