成果介绍

本发明公开了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。在本发明中，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，本发明中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。
