基于A*算法的远程导弹三维航迹规划算法

提出了一种基于A*算法的三维航迹规划方法.该方法将远程导弹的运动学模型离散化,利用导弹过载作为控制量,并结合约束条件,直接对三维空间进行最优航迹搜索.航迹规划过程不仅结合了导弹的本身机动特性,并且充分利用地形信息进行地形回避和威胁回避.仿真实验表明,该方法能够直接规划出三维空间中满足导弹过载约束的最优航迹.

3D Route Planning Algorithm for Long Range Missiles Based on A* Algorithm

This paper proposes an approach of 3D route planning based on A* algorithm.This approach could directly search optimal route in 3D environment with route constrains,which discretizes the long range missile kinematics model and uses the overload of missile as control flow.The process of route planning not only integrates the maneuverability of missile,but also adequately uses the terrain information in terrain-avoiding and threat-avoiding.Simulation results demonstrated the method could obtain optimal route in 3D environment,which could adapt to overload constrains.
