摘　　要：针对箔条质心干扰情况下雷达导引头难以可靠跟踪真实目标的问题,文中提出了一种基于距离高分辨体制的单脉冲角跟踪方法。该方法通过建立左右角度波门以获取目标的左右角偏差,再经融合处理输出角跟踪误差信号,不仅抑制了测角误差,还增加了角跟踪过程中可利用的信息量。仿真实验表明,该方法在质心干扰情况下可保持对目标的有效跟踪,是一种实用的抗箔条质心干扰方法。Since it is hard for radar seeker to track target reliably under chaff centroid jamming,a new method of angular tracking was proposed based on high range resolution. Through establishment of angle gates,this method can not only suppress the angle measurement error,but also increase the amount of information available in the process of angular tracking. In the case of centroid jamming,this method can make the radar seeker keep tracking the target reliably. Simulation results show the effectiveness of the new method.
