成果介绍

本发明公开了一种基于动态孔径的SAR虚假目标干扰抑制方法及系统，方法包括：根据的混合数据生成数据矩阵及参考信号；数据矩阵与参考信号进行成像处理，生成方位一维像，根据方位一维像生成待估计的目标点位置集合；根据预设的动态孔径窗及目标点位置集合生成动态观测矩阵；利用构造的观测表征矩阵和动态观测矩阵进行最小化求解，得到分离的真实目标点向量对应的真实方位一维像和虚假目标点向量对应的虚假方位一维像；重复上述过程，得到重构后的真实目标二维图像与虚假目标二维图像。本发明在不提高现有雷达系统复杂度的前提下，通过构建欺骗干扰分离问题的目标函数并进行优化求解，有效抑制了虚假目标的干扰，降低了系统升级的高昂开销。
