%X 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.
