摘要
针对传统机载反向交叉眼干扰有苛刻的参数容限要求的问题,提出当飞机发现被导弹跟踪时,飞机抛洒搭载反向交叉眼干扰机的干扰诱饵对制导雷达进行干扰的方法.首先建立了基于干扰诱饵的反向交叉眼干扰模型,然后推导出雷达指示角与干扰基线长度、干扰诱饵的位置、两路干扰信号的幅度比和相位差有关,最后进行了仿真.仿真结果表明,在一定的条件下,基于干扰诱饵的反向交叉眼干扰的干扰效果优于传统机载反向交叉眼干扰的干扰效果,且参数容限需求宽松于传统机载反向交叉眼干扰的参数容限.
Traditional airborne retrodirective cross-eye jamming has strict parameter tolerance requirements.In view of this situation,the paper proposes a method of jamming guidance radar with the aircraft throwing jamming decoy of the retrodirective cross-eye jammer when the aircraft is found to be tracked by missiles.Firstly,the model of retrodirective cross-eye jamming based on jamming decoy is established,and then it is deduced that the radar indication angle is related to the length of jamming baseline,the position of jamming decoy,the amplitude ratio and phase difference of two jamming signals.Finally,the simulation is carried out.The results show that under certain conditions,the jamming effect of retrodirective cross-eye jamming based on jamming decoy is better than that of the traditional airborne retrodirective cross-eye jamming,and that the parameter tolerance requirements are less stringent than that of the traditional airborne retrodirective cross-eye jamming.
