为了对付日益发展的导弹防御技术 ,再入弹头通过机动来提高生存机会。本文研究一种弹道机动方法—螺旋机动 ,首先分析其产生机理 ,然后通过反馈线性化方法实现螺旋机动的控制过程 ,最后通过实例仿真说明螺旋机动具有良好的突防能力。 In response to the growing missile defense technology, reentry warheads improve mobility by maneuvering. In this paper, we study a ballistic maneuver-helix maneuver, first analyze its generation mechanism, and then control the helicopter maneuver by feedback linearization method. Finally, an example simulation shows that helical maneuvering has a good penetration ability.
