摘要: 为实现飞行器冲突风险的实时检测,建立一种基于分组的飞行器短期冲突对快速检测算法。通过对飞行器所在高度层的4 组正方形划分覆盖来构造子空间,借助哈希表实现检测目标的快速分组,并判断飞行器之间的距离是否小于最小安全间隔,若小于则提取全部冲突对。实验表明:该算法可有效避免遗漏飞行器冲突对,显著减少检测次数,验证了算法的优越性。

Abstract: In order to realize real-time detection of aircraft conflict, a group-based aircraft conflict-pair fast detection algorithm is established. The algorithm uses four square-divided cover sets to construct subspaces in a certain altitude. Hash table is used to accelerate the grouping process. Judgments are taken in each group, and then aircraft conflict-pairs are extracted only if the distance between two aircrafts is less than the given safe interval.Simulation result shows that this algorithm can avoid missing conflict-pair and reduce detection times, validating its superiority.

Key words: air traffic control, aircraft conflict, short-term conflict detection, conflict-pair detection, spatial coverage
