攻击地面群目标的空地导弹雷达与红外复合制导方法

摘要

In a single radar guidance mode,air-to-ground missiles often fail to attack the ground targets since the radar seeker can't lock onto a target in the terminal guidance phase.To solve this problem,a radar/infrared compound guidance antenna radar seeker model and a six radiometer infrared seeker model are established,and a radar/infrared compound guidance scheme is designed,including radar guidance,radar/infrared compound guidance and infrared guidance.The attack effects in single radar guidance mode and composite guidance mode are analyzed by comparing the seeker angle error,missile overload and miss distance parameters.It is found that,under the condition of a large number of targets,the missile in compound guidance mode is more stable in overload and has higher hit accuracy compared with the single radar guided mode.%单一雷达制导的空地导弹在攻击地面群目标时,往往因为末制导阶段雷达导引头不能锁定单一目标而导致攻击失败.针对该问题,提出一种雷达与红外复合制导方法.建立四波束天线雷达导引头模型和六辐射计红外导引头模型,设计一套包含雷达单独制导、雷达与红外共同制导和红外单独制导3个阶段的雷达与红外复合制导方案,实现空地导弹对地面群目标攻击过程的仿真.以导引头误差角、导弹过载以及脱靶量为指标,对比分析单一雷达制导模式和复合制导模式下的攻击效果.仿真结果表明,在目标数量较多的情况下,相对于单一制导模式,复合制导模式下的导弹过载更稳定,命中率更高.
