摘　　要：针对中远程导弹中末制导交班过程中的弹道交接问题,基于交接过渡段制导的思想设计了一种新的中末制导交接律。首先给出了满足导弹弹道一阶和二阶平滑的条件,然后分别采用三角函数和多项式函数形式的交接律平滑算子作为加权系数,求解出满足弹道平滑条件的平滑算子具体表达式。仿真结果表明:所设计的中末制导交接律算法简单,适用于导弹攻击过程中不同阶段制导律的弹道交接及实现中末制导交接过程中的弹道一阶和二阶平滑交接。Aiming at the traj ectory shift of medium and long range missile in the course of midcourse and terminal quidance handover,a new shifted-law was designed based on the idea of shifted-guidance.The smooth transition conditions of traj ectory were put forward,and the trigo-nometric function and polynomial function were introduced in the shifted law as acceleration weight-coefficient,and the expression of the smoothness operator was presented concretely. Simulation results show that this shifted law is simple,and it can be applied to traj ectory shift to realize smooth transition of midcourse and terminal guidance handover.
