摘　　要：针对在ADS-B空域监视系统下,利用有向元胞自动机模型模拟空域,研究了飞机自主导航和飞行冲突解脱的问题。在考虑了飞机的飞行性能、最小安全间隔及飞行速度等限制条件下,建立了空域的网格模型。利用ADS-B技术,建立了有向元胞自动机运动规则,确定了有向元胞自动机的最佳运动方向,构建了飞机空中导航和空域冲突解决的算法。通过对避开空中限制区和3架飞机空中冲突解脱的仿真,给出了空中的导航路径。仿真结果表明,该算法是可行的。In order to cope with autonomous navigation and flight conflict resolution under the automatic dependent surveillance broadcast（ ADS-B） airspace surveillance systems,a new navigating and resolving conflict algorithm was proposed based on the cellular automata（ CA） model to simulate the airspace.Considering the flight performance,minimum safety interval,speed restrictions and so on,the airspace was established by the grid model. By using ADS-B technology,establishing the movement rule of directional cellular automata and determining the best moving direction,the aircraft air navigation and spatial conflict resolution algorithm was built. Through the simulation of one aircraft avoiding the restricted zone and three aircraft conflict resolution in the simulation system,the flight paths are given and the results show that the algorithm is feasible.
