| 摘要: |
| 理论推导了不同阶数假目标的相位特性及影响因素,根据单脉冲雷达角度测量的原理，分析了间歇采样转发假目标实现角度欺骗干扰的制约条件，推导了实施角度欺骗相干干扰需要满足的相位相干、幅度匹配等要求，并进一步研究了为实现相干干扰对间歇采样转发延时、转发频率、转发功率的约束条件。进行了仿真分析，分别讨论了相干干扰和非相干干扰两种角度欺骗干扰条件下关键参数对干扰效果的影响。结果表明，通过灵活的参数设计和合理布设，间歇采样转发假目标能有效诱偏单脉冲测角系统，这对于间歇采样转发干扰机的设计及使用具有指导意义。 |

| Abstract: |
| The phase signature of active decoy and its application in angular deception Jamming using Interrupted-Sampling Repeater Jamming(ISRJ) were investigated in detail. After the principles of ISRJ were expounded, the phase signature of different-order active decoy and the influential factors were analyzed. According to the principle of monopulse radar angle tracking, several conditions that should be met for jamming source were deduced, including the repeater power, the delay time and frequency of repeater. Then, the effects of correlative and non-correlative interference on angular deception were discussed, respectively. Simulation results show that the decoy can bait monopulse radar system by flexible parameter design. This research is beneficial to the jamming design and use of ISRJ． |
