空空导弹高抛弹道作战效能研究

为增加空空导弹的射程,设计了采用奇异摄动中制导律实现导弹迅速爬升并在最优高度上巡航的高抛弹道。建立了四种目标机动模型,通过弹道仿真,将奇异摄动中制导与弹道形成最优中制导进行对比,得到不同初始高度两种制导方式的最远初始攻击距离,分析了初始高度对高抛弹道性能的影响。仿真结果表明,所设计的高抛弹道能有效地增加空空导弹的攻击距离,进而提高导弹的作战效能。

Study on the operational effectiveness of high parabola trajectory of air-to-air missile

In order to extend the firing range of air-to-air missile,high parabola trajectory is designed to make missile ascend quickly and cruise at the optimal height by singular perturbation guidance law.Four target maneuvering models are built.Through trajectory simulation and contrast between singular perturbation guidance law and trajectory shaping optimization guidance law,the farthest initial striking distances of the two missile guidance modes are obtained from different initial height,as well as the effect of initial height on the performance of high parabola trajectory is analyzed.The result of simulation shows the striking distance of air-to-air missile is extended effectively by the high parabola trajectory designed,and the fighting efficiency of missile is enhanced.
