摘　　要：机载雷达具有作用距离远和机动灵活性高等特点,目前已经成为运动目标检测的重要手段。机载雷达受波束下视工作及平台运动影响,其接收回波数据中不仅包含目标回波信号,还包含大量多普勒谱扩展的地物散射杂波。文章首先对机载雷达杂波分布特性进行分析,然后从主杂波跟踪、平台运动补偿、空时自适应处理以及工程实现4个方面对机载雷达杂波抑制方法进行综述,最后对现有方法存在不足进行总结并对未来研究方向进行展望。Due to the advantage of far-forth detected distance and high maneuverability,airborne radar has be-come an important method for moving targets detection.However,affected by both the down-looking operation of radar beams and platform motion,the received signal of airborne radar not only includes target echo,but also a large number of ground clutter with Doppler spectrum expansion.In this paper,we first analyze the distribution characteristics of airborne radar clutter.Then,we review the clutter suppression methods from four aspects,in-cluding main clutter tracking,platform motion compensation,space-time adaptive processing and engineering implementation.Finally,we summarize the shortcomings of existing methods and point out directions for future research.
