摘　　要：为了加速空管自动化与智能化技术的应用与实施,提出了水平航迹与高度/速度剖面分阶段设计的四维航迹规划方法。基于动态时间规整与层次聚类方法实现历史雷达航迹聚类分析,完成水平航迹设计。建立速度剖面规划模型,通过航迹生成器与速度调整器交互协作,精细化控制进场时间,以满足计划到达时间要求。以上海浦东国际机场PINOT进场航班为例实施验证,结果表明,四维航迹规划方法可有效实现航班的计划到达时间,从而减少航班延误,提高终端空域运行效率。In order to accelerate the implementation and application of Air Traffic Control automation and intellectualization,a two-stage 4D trajectory planning method was presented,in which the horizontal path and altitude / speed profile were designed successively. Firstly,the horizontal path was designed through clustering and analysis of the historical radar tracks based on Dynamic Time Warping algorithm and Hierarchical clustering upon which a horizontal path can be designed. Then the velocity profile programming model was established,which is based on the interaction between the track generator and the speed regulator,to control the approach time finely to guarantee the scheduled time of arrival. Finally,taking arrival flights to Shanghai Pudong Airport from PINOT entry fix as examples,a simulation was conducted. And the simulation result indicates that the proposed 4D trajectory planning method is able to increase the arrival punctuality rate,reduce flight delays,and improve the operational efficiency in terminal airspace.
