空空导弹末端非线性修正技术研究

On endgame nonlinear correction technology of air-to-air missile

针对红外空空导弹瞄准点与理想命中点不重合的矛盾,本文提出一种末端修正导引方法,修正导弹对目标的碰撞航线。导出了空间飞行时实现超前偏置的导引律,并提出简化导引律方案,对引入超前偏置的末端制导控制系统进行了分析,探讨了控制系统实现的方法。仿真表明对导引精度和脱靶量有显著提高,能达到理想的修正效果。

To solve the problem that the aiming point of IR air - to - air missile can not be kept the same as the ideal hit - point, a guidance method for amending endgame trajectory is proposed to correct hit - track of the missile- target, and also to improve guidance effectiveness and lethality. We educed the biased proportional guidance law and present a scheme for simplifying the guidance law. We also analyzed the endgame guidance control system with lead bias imported, and presented the method for realizing the control system. Simulation showed that the guidance precision was improved greatly, which could satisfy the requirement.
