摘　　要：交叉眼干扰是对导弹单脉冲跟踪的有效干扰手段,为了深入分析交叉眼干扰机理,提高交叉眼干扰系统使用的效能,对双站反向交叉眼干扰雷达测角系统引入的指示角进行推导,得到精确数值解和近似条件下数学表达式,分析了近似数学模型和精确数值解之间的误差,使用数值解对影响交叉眼干扰效果的各因素进行了分析,对双站交叉眼干扰使用场景进行了分析,在简化引导率条件下对交叉眼干扰对导弹单脉冲跟踪的影响进行了仿真。结论表明,干扰距离越近、两干扰站距离越远、相位差越接近180°,交叉眼引入的指示角越大。不同干扰场景下指示角和角度干扰效果之间的关系不同。在合理的布站及稳定的幅度比和相位差控制下,交叉眼系统对雷达测向引入的欺骗角是发散的。Cross eye jamming is an effective jamming method to missile monopulse tracking.In order to deeply analyze the cross-eye jamming mechanism and improve the usage efficiency of cross-eye jamming system,this paper educes the indication angle created by bi-station reverse cross-eye jamming radar angle measuring system,obtains the accurate numerical solution and the mathematical expressions under approximate conditions.The error between the approximate mathematical model and the exact numerical solution are analyzed,and the factors influencing the cross-eye jamming effect are analyzed by using the numerical solution.The use scene of bi-station cross-eye jamming scene is analyzed,and the effect of cross-eyes jamming on the missile monopulse tracking under the condition of simplified guidance ratio is simulated.The results show that,the closer the jamming distance is,the farther the distance between two jammers is,and the closer the phase difference is to 180°,the larger the indication angle introduced by cross-eye system is.In different jamming scenarios,the relationship between indicating angle and angle jamming effect is different.Under the control of reasonable stationing,stable amplitude ratio and phase difference,the deception angle introduced by the cross-eye system to radar direction finding is divergent.
