摘　　要：以改进型Dynapath算法为基础,运用预测控制原理,提出了一种基于滑动时间窗的航路动态优化算法。通过选择合适的数据窗口长度,在这个窗口时间内进行威胁建模,做出战场短期预测。随着时间的推移,规划窗口也相应地向前滑动。仿真结果表明,该方法实时运算数据量小,兼顾了全局航路动态最优化。The aircraft dynamic path optimization referenced the path in the whole path planning on the ground,according to the new threat and terrain.This paper proposed an improved Dynapath dynamic optimization method based on the predicted control theory.When the data window length was selected,threat models and battle information may be calculated in this time window.Along with the time flow,the time window rolled forth.This real time method got lower calculation and whole dynamic path optimization.
