摘　　要：航空器4D航迹规划可有效解决我国当前面临的航班延误问题,并且能够加速空管自动化与智能化技术的应用与实施。因此提出了1种基于历史雷达轨迹分析的4D航迹规划方法:首先利用动态时间规整与层次聚类算法对进场历史雷达轨迹进行聚类分析,复现盛行交通流,继而根据盛行交通流和标准进场航线完成水平路径设计;其次对进场历史雷达数据统计分析,确定各进场航路点的高度/速度范围,然后基于航空器在终端区尽量保持高高度飞行的原则完成高度剖面设计;再次为使航空器可以按规定时间到达指定航路点,根据各航路点的速度范围设置合理参数,通过对参数优化调整完成所需速度剖面的设计。最后以上海浦东国际机场VMB进场场景为例进行仿真验证,平均误差为2.5s,误差率为1.9‰。仿真结果表明基于历史雷达轨迹分析的4D航迹规划方法可有效实现航班的准点降落,从而减少航班延误,提高终端空域运行效率。4Dtrajectory planning can solve flight delay problems and accelerate the implementation and application of automation and intellectualization in Air Traffic Control.4Dtrajectory planning based on analysis of historical radar tracks was proposed.Historical radar tracks were clustered and analyzed by Dynamic Time Warping algorithm and Hierarchical clustering.Horizontal paths were designed based on the reproduced traffic flow and standard arrival routes.The ranges of altitudes and speeds of aircrafts were determined by statistical analysis of historical radar tracks.The altitude profiles were designed based on the principle of aircrafts should keeping high altitude as much as possible in the terminal area.Finally,the speed profiles which satisfy the scheduled time of arrivals were designed based on optimized parameters.Arrival flights to Shanghai Pudong Airport were selected as a simulation scenario as a result of the mean error of 2.5sand the margin of error of 1.9‰.The simulation result indicates that the proposed 4Dtrajectory planning method can achieve flights landing punctuality,reduce flight delays and improve the efficiency of the terminal airspace.
