空空导弹攻击防区外目标研究

Study on attacking of targets beyond defense area with air-to-air missiles

在对防区外发射武器载机特性分析的基础上 ,基于一定的假设 ,提出了远距空空导弹攻击超视距目标的总体模型。从建立与目标机、远距空空导弹、本机相应的各种坐标系入手 ,分别建立了目标机、远距空空导弹、本机的运动模型和远距空空导弹的制导模型。依据所建立的系统模型和扩展比例导引算法 ,利用最优控制理论求出了最优导引律。经计算机仿真可以看出在作战飞机常用的作战高度、空战速度范围内 。

Based on analysis to characteristics of targets outside the defense area and some assumptions, a general model of attacking maneuvering targets beyond visual range with long range air to air missile is presented. With corresponding coordinate systems, the target aircraft model, long range air to air missile model, moving model of the attacking aircraft and the guidance model of long range air to air missile are built. Based on the models and the expanded proportion guidance algorithm and by using theory of optimal control, the optimum guidance algorithm is found out. The simulating result shows that the long range air to air missiles really have the air defense capability beyond visual range at normal fighting height and speed.
