以评估美国国家导弹防御(NMD)系统雷达识别能力为背景，分析了地基雷达识别弹道导弹目标的技术途径。根据弹道导弹目标群在飞行中段和再入段表现出的特性差异，提出了涉及目标结构特性、姿态特性以及再入特性的综合识别策略，并初步分析了各种识别措施的可行性。

The technology of the radar discriminating ballistic missile is analyzed so as to evaluate the discrimination capability of ground-based radars in the US National Missile Defense (NMD). According to the characteristics of the ballistic target clusters during the mid-course and re-entry phase, an integrative discrimination strategy for the missile defense system is developed which involves the structure, stance and re-entry characteristics of the target, and each discrimination measure is followed by technical evaluation.
