空空导弹攻击超视距空中目标仿真研究

通过对超视距空中机动目标的分析和合理的假设之后,提出了用空空导弹攻击超视距空中目标的基本模型。从建立目标机、空空导弹、载机的适当坐标系入手,分别给出了目标机、空空导弹及其制导模型、载机的运动模型。建立所给定空空导弹攻击系统的总体模型,对空空弹采用扩展比例导引算法,利用最优控制理论导出最优导引律。经仿真验证证明在作战飞机常用的作战高度、空战速度范围内,用远程空空导弹来攻击超视距空中目标是完全可以实现空中防御的。

Study on Simulation of the Attacking Ability of Air to Air Missiles for Beyond Visual Range Targets

Based on the analysis of the characteristics of air maneuvering targets beyond visual range and some reasonable assumptions, a model of air to air missile for attacking air targets beyond visual range is presented. Beginning with various corresponding coordinate systems of the target aircraft model and the air to air missile model, the moving models of the target aircraft and the attacking aircraft, and the guide model of air to air missile are built respectively. By making use of the expanded proportion guide algorithm and the optimal control theory, an optimum guide algorithm is found out. The simulating result shows that the long-distance air to air missiles really have the air defense ability in common fighting height and speed.
