摘要
交叉眼干扰是一种能够有效对抗单脉冲雷达的角度欺骗干扰.针对不同收发分置结构的两点源反向交叉眼干扰系统,考虑干扰机平台旋转的影响,建立不同天线结构的干扰信号传播路径模型,通过理论分析和仿真实验研究了不同结构模型对干扰性能的影响,验证了模型分析与实验结果的一致性.仿真实验结果表明:干扰机平台的旋转角度以及干扰机与雷达间的距离等参数对不同天线结构的干扰机性能有着不同的影响,对反向交叉眼干扰系统的工程设计具有一定的参考价值.
Abstract
Cross-eye jamming is an effective angular deception jamming technique used for countering mono-pulse radars.In the case that the jammer platform rotates in all different directions,the interference signal propa-gation path models are established by analyzing dual-source retro-directive cross-eye signal propagation paths based on two antenna structure models.The effect of various parameters on the cross-eye jamming is discussed through the rigorous mathematical derivation and theoretic analysis and given through case simulation for the dif-ferent scenario.The following conclusions are demonstrated by the simulation results:under condition of the pa-rameters such as the rotation angle of the cross-eye jammer platform and the distance between the radar and the platform,the phase can be changed caused by wave path-difference and the antenna structure.Some reference can be provided for the design of reverse cross eye jammers.
