摘要
讨论在多径环境下 ,被动雷达导引头对噪声调频干扰源的角度跟踪方法。在窄带噪声调频干扰源条件下 ,利用大信号法实现真实干扰源的角度跟踪 ;在宽带噪声调频干扰源条件下 ,利用聚类分析法实现真实干扰源和镜像干扰源的角度分辨 ,从而使导引头正确跟踪真实干扰源。计算机仿真结果证实了这两种方法的有效性和正确性。
Methods of multipath jammer tracking with a passive radar seeker are presented in this paper. In the presence of a narrow band noise frequency modulation (FM) jammer, angle tracking to a real jammer is realized by using the big signal method. In the case of a wide band noise FM jammer, angle resolving to real and image jammers is realized by using the clustering method. These two methods are verified by the results of computer simulation.
