红外空空导弹是最有效的近距空战杀伤武器，但其工作机理复杂，干扰环境多变，仿真出来的导弹很难与真实导弹的性能相符。为了简化仿真过程、提高仿真结果的准确性，摒弃复杂的物理仿真从导弹的功能仿真切入，注重导弹的识别、导引、控制、运动过程。首先建立基于三自由度的导弹数学模型，简化导弹运动方程；其次将抗干扰方法分类，分析导引头进入抗干扰状态和没进入抗干扰状态抗干扰的不同机理；最后建立以导弹、诱饵、飞机为主体的仿真平台，以脱靶量、导弹轨迹、抗干扰概率做为仿真结果的评价标准。仿真结果表明，仿真的红外空空导弹模型简单、易于实现、抗干扰结果与真实导弹接近，能够满足空战评估的基本要求。

Infrared air- to- air missiles are the most effective close combat destructive weapons, but their working mechanisms are complex, jamming environment are variable, so the simulation missiles are hard to match the real. To simplify the simulation process and improve the accuracy of the simulation results, start from missiles functional simulation and abandon the complicated physics simulation, only concentrate on identification, guidance, control and motion process. Firstly, missile mathematical models were established based on the three degrees of freedom to simplify missiles motion equations. Secondly, the anti- interference method was classified, analysed different anti- interference mechanisms between the seeker entered into anti- interference state and couldnˊt enter into. Lastly, the simulation platform to the missile models, bait models and aircraft models as the core were established and miss distance, missile trajectories, anti- interference probability were used as evaluation criteria of simulation results. The simulation results show, the simulation infrared air- to- air missile models are simple and easy to implement and anti- interference results are close to the real missiles, also can meet the requirements of combat assessment.
