中远距空空导弹导引头系统仿真及误差分析

Simulation and error analysis of medium-long-range air-to-air missile seeker system

针对中远距空空作战,建立了中远距空空导弹的飞行仿真模型,给出了导弹攻击目标的全过程,并给出了攻击结果,即脱靶量和目标杀伤概率的计算方法。在分析末制导阶段导弹雷达工作过程的基础上,分析了导引头误差对测量目标信息及导弹飞行过程和攻击结果的影响。最后,使用Visual Studio 2010和OpenGL进行了空空导弹的全过程飞行仿真,验证了模型的正确性和有效性。

For the medium-long-range air-to-air combat,the flight simulation model of medium-long-range air-to-air missile is specially established and the whole working process of a missile attacking a target is described.The method for calculating the attack results(i.e.,miss distance and the lethal probability)is given.By analyzing the working process of the missile radar in the terminal guidance phase,this paper analyzes the radar seeker error influencing on the target information,missile flight process and attack results.Finally,the Visual Studio 2010 and OpenGL are used to simulate the missile flight and validate the validity and correctness of the model.
