摘　　要：针对宽带毫米波雷达中的目标角跟踪问题,介绍了一种毫米波雷达单脉冲跟踪仿真系统。该系统模拟了导弹高速跟踪面目标的角闪烁情况,并采用高距离分辨率的α-β距离滤波和频率捷变角度平滑进行了跟踪处理。结果表明该仿真系统较好地抑制了面目标的角闪烁,提高了单脉冲跟踪精度,对解决面目标的导弹跟踪问题具有实际意义。In view of the glint of the wide- band millimeter wave（MMW） radar in angular tracking, a monopluse tracking simulation system for MMW radar is presented. The system simulates the glint when missile tracks surface targets with high speed and the return signal is processed by α-β filter based on high resolution range profile and angle smoothing based on frequency agility. Computer simulation proves that the simulation system greatly suppresses the angular glint of surface targets and improves the angular accuracy. It is instructive for solving the problem accuring when missile tracks surface targets.
