针对导弹带落角约束条件打击目标的要求,在纵向平面内,根据导弹和目标的实时运动轨迹,提出了一种虚拟目标实时轨迹生成算法,并且给出了该算法中所需要的目标实时位置信息的估算方法.仿真结果表明,以该算法得出的虚拟目标轨迹作为导弹的跟踪对象,采用变结构导引律能满足落角约束条件,并且能够提供很高的命中精度,从而证明了该算法的正确性和有效性,为带落角约束条件打击目标提供了一种新的思路和途径.

Research on Real-Time Algorithm of Waypoint Generation for a Virtual Target on Hitting Targets with Impact Angle Constraint

Considering the request of impact angle constraint of the attacking missile,an real-time algorithm of waypoint generation for a virtual target is deduced based on the movement of the missile and target on the vertical plane.The trajectory of virtual target is used to guide the missile with variable structure control(VSC) guidance law.Besides,a real-time information estimation method of the coordination is given.At last,the simulation has been made,the results show that if the virtual trajectory is used to guide the missile with VSC guidance,the miss distance is very small and the impact angle constraint can be satisfied.As a result,the effectiveness and rightness of the algorithm is proven,and a new way of hitting targets with impact angle constraint is given.
