A novel ISAR jamming method based on randomly sinusoidal phase modulation

In order to jamming ISAR imaging effectively, a novel jamming method based on randomly sinusoidal phase modulation is presented in this paper. This method changes randomly the frequency of the signal of sinusoidal phase modulation in the slow time. How the jamming signal affects the range alignment of ISAR is analyzed in detail. The research result shows that the jamming method can destroy severely the range alignment of ISAR and realize the unfocused image barrage jamming to ISAR. Furthermore, the validity of the jamming method is justified by simulation experiment.
