为了在未来高技术战争中制导武器得到有效的防护和提高战斗力,针对高功率微波武器(HPMW)对步进频率线性调频(SF-LFM)脉冲压缩雷达单脉冲测角性能的影响,首先提出了HPM作用情况下雷达接收机和差通道信号模型,然后对雷达系统的数字脉冲压缩以及单脉冲测角等信号与信息处理过程进行仿真实现,通过蒙特卡罗实验得到相关数据,建立起测角精度与HPM所引发的相位噪声的强度与相关性之间的定性与定量关系,给HPMW设计与应用的相关单位提供参考依据。

To effectively protect guided weapons and improve the combat effectiveness in the future high-tech war. Angle estimation of monopule in SF-LFM pulse compression radar will effected by the high power microwave weapon. First, this paper proposes the radar-receiver sum and difference channels moddel on which the HPM effects, then simulates radar system signal and information processing like digital pulse compression, monolulse angle estimation. Obtained data from Monte-Carlo experiments, this paper builds the qualitative and quantitative relations between accuracy of the angle measurement and strengh and correlation of the phase noise caused by HPM. These conclusions can provide reference for some HPMW design and application units.
