摘　　要：速度真值计算是脉冲多普勒雷达信号处理领域的一个重要问题。常用的脉冲多普勒雷达解速度模糊方法中,重频提高方法会导致距离模糊,重频参差方法会造成雷达资源的浪费。提出了一种基于目标特性的速度真值计算方法,利用雷达回波数据得出目标的模糊速度及速度模糊次数,结合两者求得目标的高精度速度真值。实验结果表明,利用所提方法能够在速度模糊的情况下解出速度真值。The calculation of true velocity is an important issue in the field of pulse Doppler radar signal processing.In the conventional methods resolving velocity ambiguity for pulse Doppler radar,the method increasing repetition frequency may lead to distance ambiguity,while the method of staggered repetition frequency may cause wastage of radar resources.This paper proposes a velocity truth calculation method based on target characteristics,which uses radar echo data to obtain the target’s fuzzy velocity and the velocity ambiguity frequency,and combines the both to obtain the high-precision velocity truth value of the target.The experimental results show that the method proposed can solve the true value of velocity in the case of velocity ambiguity.
