摘　　要：为了实现终端区航班无冲突进场航迹的自动生成,提出了基于管制策略的4D进场航迹规划方法。通过基于进场耗时的层次聚类算法对历史雷达轨迹进行分析,提取包含管制意图的盛行水平路径;根据管制引导策略对进场程序航段分类,建立水平路径调整模型,结合各机型连续下降进近垂直剖面,生成无冲突4D进场航迹。以国内某机场为例,聚类分析进场航班,并对其进场程序建模仿真。结果表明,上述法可以实现终端区进场程序的动态调整,在满足各类间隔约束的条件下,为每架进场航空器规划出无冲突航迹。In order to realize the automatic generation of collision-free approach trajectory in the terminal area, a 4 D trajectory planning method based on control strategies was proposed. The historical radar trajectory was analyzed by a hierarchical clustering algorithm based on approach time-consuming, and the prevailing horizontal path containing the control intention was extracted. The STAR segments were classified according to controllers’ vectoring strategies and a horizontal path adjustment model was established.Combined with each aircraft’s continuous descend vertical profile, the collision-free 4 D approach trajectory was planned. Taking a domestic airport as an example, we analyzed its approach flights by clustering and the approach procedure was modeled and simulated. The results show that the method can realize the dynamic adjustment of the approach procedure in the terminal area. Collision-free trajectory meeting various intervals can be planned for each approaching aircraft.
