| 摘 要： | 脉冲重复间隔测量误差将导致干扰机发射与SAR接收之间无法保持同步，这将对干扰效果产生不利影响，研究这些影响对于SAR干扰机的研制与应用来说具有重要的参考价值。在此背景下，建立了脉冲重复间隔测量误差和干扰信号模型，推导了测量误差与假目标图像成像形状、位置和分辨率关系的解析表达式，分析了有可能出现的干扰结果。仿真实验验证了理论分析的正确性。

| Abstract: | Due to the measurement error of Pulse Repetition Interval (PRI), the non synchronism between the jammer transmitter and the Synthetic Aperture Radar (SAR) receiver has harmful influence on the jamming effect. It is valuable to study the influence for the development and application of deceptive jammer. Based on the background, the PRI measurement error and jamming signal models are established in this paper. The analytic expressions between the PRI measurement error and shape location and resolution of the deceptive target image have been deduced and possible jamming results are analyzed detailedly. The correctness of theoretical analysis is proved by the simulation experiment. |
