摘要
提出了一种基于闭路制导的弹道导弹的发射诸元算法。给定发射点与瞄准点的地理位置,以压低弹道为目标,通过一种迭代方法求解关机点弹道倾角,并基于地球引力级数展开模型提出了一种虚拟目标的快速计算方法,以主动段弹道平面和被动段弹道平面二面角为指标完成了发射方位角的迭代计算,最后通过仿真算例论证了该算法的可行性。
An effective approach for computing the basic firing data of ballistic missiles based on close-loop guidance law was presented.If the launch position and aiming position were given,velocity obliquity could be gotten by iterative method aiming at depressing trajectory.Based on gravitational series model,a new scheme was proposed to calculate virtual target.In the process of calculating optimal azimuth angle,dihedral angel was introduced into the iterative algorithm which improved computing velocity with no loss of firing accuracy.Finally,the feasibility of this approach was demonstrated by numerical simulation study.
