以相控阵雷达对低空/超低空目标跟踪为背景,研究相控阵雷达低角跟踪方法。首先介绍了低空多径效应的机理、雷达跟踪低空目标时的难点和常用的低角跟踪技术,基于相控阵雷达的波束位置、发射频率对低角跟踪的影响,提出了一种基于相控阵雷达的多波束低角跟踪方法,通过对典型低空目标跟踪的仿真对比,证明此方法能够有效提高雷达低角跟踪精度。

This paper studies a low angle tracking method of phased array radar based on the background of low and ultra-low altitude target tracking.Firstly,the principle of low altitude multipath effect,the difficulty of radar tracking low altitude target and common low angle tracking technology are introduced.Based on the influence of beam position and transmission frequency of phased array radar on low angle tracking,a multi-beam low angle tracking method based on phased array radar is proposed,and the simulation comparison of typical low altitude target tracking shows that this method can effecitvely improve the low angle tracking accuracy of radar.
