摘　　要：目标的速度及其加速度是弹道导弹防御相控阵雷达鉴别真假弹头的的重要特征量,同时对宽带雷达的一维距离像的速度补偿提供必要的信息。该文根据相控阵雷达多目标数据率低的特点,提出了细谱线目标速度精确测量的数字实现方法;分析了在目标截获中脉冲相关法与通道补偿法两种估计加速度方法的性能,并提出了解速度模糊的新方法,分析和计算结果表明所提出的速度截获和解模糊方法是可行的。Velocity and acceleration of target are regard as these of the most important features in real and artificial warhead recognition for ballistic missile defence phased array radar, and also are used as the necessary information for velocity compensation of onedimensional range profile in wideband radar. Based on the property of low data rate of phased array radar, this paper proposes a digital method to achieve fine-line velocity tracking, and the performances of pulse correlation and channel compensation, two methods being useful for acceleration estimation in target acquisition, are analysed. A new way to solve velocity ambiguity is also proposed.The simulation proves that all the methods are correct and efficient.
