Study on Clutter Suppression Algorithm for Airborne Radar with Non-sidelooking Arrays

  • 摘要: 非正侧视阵机载雷达的空时二维杂波谱随距离的变化而变化,即在距离维是非均匀的,因此不能直接由邻近距离单元估计杂波协方差矩阵。为了解决这种由距离依赖性引起的杂波特别是近程杂波的非均匀问题,该文对多普勒频移算法进行了改进,将经过多普勒频移补偿后的数据转换到阵元-多普勒域,在多普勒域进行空间频率补偿,提高其在主杂波区的性能。改进算法既充分利用了原算法简单,易于实现的特点,又克服了原算法在大偏航角下性能下降的缺陷,仿真结果验证了该算法的有效性。
