摘　　要：复杂的空间目标群给雷达目标识别带来了挑战。分析了弹道中段空间目标群的构成及其对识别的挑战。系统归纳了反导中段雷达目标识别方法。根据雷达识别所采用的特征不同,将空间目标雷达目标识别方法分为其于结构特征的识别方法、基于弹道特征的识别方法和基于微动特征的识别方法,详细阐述了这3类识别方法的物理基础及其特征提取方法,分析了各种识别方法的特点,最后展望了中段雷达目标识别的发展趋势。The complexity of space target brings in some challenges for radar target recognition. The element of space environment in midcourse is analyzed and the difficulties for radar target recognition are expounded. According to different features used by radar, those methods are divided into three catego- ries, namely, methods based on configuration feature, macrodynamics feature and microdynamic feature respectively. The physics foundation and research progress of the three methods are expounded and their characteristics are discussed respectively. Finally, the future tendencies of radar target recognition development in midcourse are forecast.
