基于效能评估的战斗机末端光电对抗仿真

Electro-optical countermeasure simulation of fighter terminal based on effectiveness evaluation

为掌握战斗机末端光电威胁交战场景,评估无源干扰手段使用样式策略和效能,采用集对分析和粗糙集理论的综合评估方法,研究了不同类型和数量来袭导弹时威胁等级和威胁排序实现算法。同时对飞机、多点源诱饵、伴飞诱饵及面源诱饵干扰特性的建模计算进行了分析研究,生成飞机与多点源、伴飞及面源诱饵相互影响的红外对抗场景。利用告警等级模型评估的威胁等级自适应决策出无源干扰的使用策略,并能对战斗机末端光电手段进行干扰效能评估。结果表明:能实时生成不同帧频下的战斗机末端红外对抗场景;根据威胁等级排序决策能力,对多点源、伴飞和面源诱饵使用策略和干扰效能进行有效评估。

To master the combat scenarios of theelectro-optical threat at fighter terminal,evaluate the use style strategies and performance of passive jamming methods,the comprehensive evaluation methods of set pair analysis and rough set theory was adopted to study the threat levels and threat sequencing implementation algorithms when different types and numbers of incoming missiles were attacked.Meanwhile,the modeling and calculation of the interference characteristics of aircraft,multi-point source decoys,escort free-flight decoys and surface-type infrared decoy were analyzed and researched;an infrared countermeasure scene was generated in which the aircraft and multi-point source decoys,escort free-flight decoys and surface-type infrared decoy interact with each other.The threat level evaluated by the alarm levelmodel was used to adaptively decide the use strategy of passive jamming,and could evaluate the interference effectiveness of theelectro-optical means of the fighter terminal.The results show that it can generate real-time infrared countermeasure scene of fighter terminal at different frame rates;according to the decision-making ability of threat ranking,the use strategy and jamming effectiveness of multi-point source,companion and non-point source decoys are effectively evaluated.
