| 摘 要： | 首先给出了ISAR雷达的匀速直线运动目标的成像模型,分析了成像原理,根据发射的LFM信号的特点,提出了针对距离维的卷积干扰,理论分析了卷积干扰机理,证明卷积干扰对ISAR雷达具有显著的干扰效果。根据视频信号的不同,干扰机能产生假目标欺骗干扰和噪声覆盖干扰两种效果。仿真实验表明理论分析的正确性和实际应用的可行性。

| Abstract: | The article first presents the imaging model of ISAR radar objects with uniform linear motion,then analyzes the imaging principles.According to characteristics of the LFM signal emitted,convolution jamming against distance-dimensional is proposed.Then the article theoretically analyzes mechanism of convolution jamming and proves it has notable jamming effects against ISAR radar.According to different video signals,jamming mechanism generates two jamming results:false targets deception jamming and coverage noise jamming.Simulation experiments show correctness of theoretical analysis and feasibility of practical application. |
