| 摘 要： | 本文提出了一种新的飞行器三维航迹规划方法－SDS。该方法能够在具有预先未知威胁的飞行环境中在线实时航迹规划。当飞行器上装备的探测器探测到飞行环境中有预先未知的威胁出现时，根据探测到的信息及时更新威胁数据。SDS根据新的环境信息局部修正受到影响的航迹段来获得新的全局最优航迹。在每一时刻考虑当前已知的信息下，SDS生成的航迹是满足要求的最优航迹。

| Abstract: | A new 3D route planner for aircrafts,SDS is presented.This approach can be used for on line route re planning in flying environment with unknown threat.It can update threat data in real time when the sensor equipped on UAV perceive an unforeseen threat and update the route locally to obtain the globally optimal route using new information acquired.Considering all known information at every moment,the SDS algorithm can generate desirable optimal route. |

| Keywords: | Real time plan Dynamic threat avoid 3D route |
