分导策略即研究一发火箭发射多个分别沿不同轨道瞄准不同目标或同一目标飞行器的方法,首先分析弹道特点,然后分别对纵向距离分导、横向距离分导、纵横向距离同时分导、对同一落点的分时分导、两次以上的分导等5种不同分导策略,利用卫星轨道力学理论逐一开展分析并推导速度增量的计算方法,最后给出基于速度增量在参考坐标系上的偏导数投影得出最优的分导策略控制方法。
The sub-guide strategy is to study a rocket launching multiple methods of aiming at different targets or the same target aircraft along different orbits. Firstly, the characteristics of the trajectory are analyzed. Then, the guidance of the vertical distance, Time-division guidance of the same point of placement, and guidance of more than two times in five different guidance strategies, the use of satellite orbital mechanics to analyze and deduce the calculation method of speed increment one by one, and finally, based on the speed increment in reference coordinates Department of the partial derivative of the projection derived optimal control strategy of sub-guide.
