如果导弹要从已对准的某一个打击目标转换到另一个打击目标, 重新定位瞄准则严重影响了导弹的机动发射能力。基于弹载射向变换的基本原理, 建立了导弹的射向变换模型, 提出了通过在弹道主动段滚动弹体实现射向变换的方法。仿真结果表明, 该模型可以实现弹道导弹主动段射向变换, 设计的仿真系统具有一定的抗干扰性, 且滚动角指令跟踪效果好, 导弹能够稳定飞行。

If the missile is converted to attack another target once it has aimed at one target, the repositioning will have a very serious impact on maneuvering capability of the missile. Based on the basic principle of the firing direction change of the missile body, this paper establishes a model of missile firing direction change, presents a method to realize the change by rolling of missile body in the boost phase. The simulation results show that: 1) The model can achieve the direction change in boost phase of ballistic missile; 2) The designed simulation system has certain anti-interference capability, and rolling angle command tracking effect is fine;and 3) The missile can fly steadily.
