基于弹目交会过程仿真的近距空空导弹脱靶量分析

Miss Distance Analysis for Short-range Air-to-air Missile-target Engagement

为对近距空空导弹脱靶量的影响因素进行分析,在六自由度弹道模型的基础上,以导弹拦截盘旋机动目标为例,建立了弹目交会仿真模型,分别就弹目初始距离、初始高度对导弹脱靶量的影响进行了仿真分析。在此基础上,对导弹在弹目交会过程中的相关参数进行了分析,给出了上述初始条件变化下导弹脱靶量的变化原因。仿真发现:弹目初始距离过大或过小均会产生较大的脱靶量;低空时脱靶量随初始高度的升高先减小后保持稳定,当高度较高时,脱靶量随着高度的升高会出现一定程度的波动,当高度过高时,导弹开始丢失目标,脱靶量急剧增大;以上结论与弹目交会过程中导弹的速度、过载稳定性有关,能够为空空导弹的作战使用提供参考。

In order to analyze the influence factors of miss distance for short-range air-to-air missile,on the basis of six-de⁃gree-of-freedom trajectory,a missile-target simulation model is established especially for missile intercepting circling target.The effects of initial range,initial altitude on miss distance are analyzed.Besides,the relevant parameters of missile in the process of en⁃gagement are analyzed to obtain the reason for the variety of miss distance with respect to above initial conditions.Simulation shows that too large or too small initial range will both produce large miss distance.At low altitude,miss distance decreases with initial alti⁃tude and then remains stable.When initial altitude is higher,the miss distance will fluctuate with altitude increasing,as initial alti⁃tude becomes too high,the missile starts to lose the target and miss distance increases sharply.The above conclusions are related to the speed and overload stability of the missile during the engagement process,which can provide a reference for the combat use of air-to-air missiles.
