Tolerance sensitivity limits the practical application of the cross-eye jammer. Previous literature has demonstrated that retrodirective cross-eye jamming with multiple antenna elements possesses the advantage of loose tolerance requirements compared to traditional cross-eye jamming. However, the previous analysis was limited, because there are still some factors affecting the parameter tolerance of the multiple-element retrodirective cross-eye jamming (MRCJ) system and they have not been investigated completely, such as the loop difference, the baseline ratio and the jammer-to-signal ratio. This paper performs a comprehensive tolerance analysis of the MRCJ system with a nonuniform-spacing linear array. Simulation results demonstrate the tolerance effects of the above influence factors and give reasonable advice for easing tolerance sensitivity.

多元素线性反向交叉眼干扰容限分析

容差灵敏度限制了交叉眼干扰器的实际应用。先前的文献表明，与传统的交叉眼干扰相比，具有多个天线元件的反向交叉眼干扰具有容差要求宽松的优势。然而，之前的分析是有限的，因为仍然存在一些影响多元素逆向交叉眼干扰（MRCJ）系统的参数容限的因素，并且还没有完全研究它们，例如环路差异，基线比和干扰信号比。本文对具有非均匀间距线性阵列的 MRCJ 系统进行了全面的公差分析。仿真结果证明了上述影响因素的容差效应，并给出了缓和容差敏感性的合理建议。
