偏移链路诱偏反辐射导弹效能分析

基于偏移寻的点对抗反辐射导弹(ARM)的基本思想,提出偏移链路诱偏ARM的方法,给出ARM的分辨距离及导向雷达的概率计算模型及方法,以三单元偏移链路为例,绘制概率树,建立偏移链路诱偏ARM的作战效能评估模型,计算分析辐射源的工作时间、间距、ARM速度和分辨角等因素对诱偏效果的影响,给出了关系曲线,验证了偏移链路对抗ARM的合理性和有效性.与采用同时辐射的附加辐射源相比,偏移链路对导引头输入端信号等幅度要求不严,对辐射源的功率、相位要求不高,实施方案更容易,不用考虑各辐射源的相互影响,对辐射源的控制较容易实现.

Effectiveness analysis of excursion link decoy against ARM

Based on the theory of homing point excursion link against anti-radiation missile(ARM),a method of decoying ARM by excursion link was proposed,and the mathematical model on calculating the ARM's resolution distance and guiding probability was established.The operational effectiveness assessment model of 3 unit excursion link was presented,then the influence of radiant points' working time,distance,ARM's resolution angle and velocity on decoy effect was analyzed and the relation curves were given.The results show this method is effective.Compared with the additive radiant points working together,the excursion link decoy doesn't require the equal amplitude signals in seeker input and the accordant power and phase for radiant points,so the project is easier to be carried out,and every radiant point doesn't influence each other,it is also facile to control them.
