摘　　要：四维(4D)航迹预测技术能提前确定航空器下一时刻的位置和到达时间,是高密度航空器运行环境下对空域进行管理的基础。我国作为国际上主要的航空大国之一,面对日益增加的民航航空器数量和飞行流量的增加,进行四维航空器航迹预测技术的研究已刻不容缓。文章介绍了四维航迹预测技术的重要意义以及其发展,国内外的研究现状,进而总结出我国在四维航迹预测研究方面的一些优缺点以及有待进一步研究的技术。Four-dimensional(4D)trajectory prediction technology can determine the position and arrival time of the aircraft at the next moment in advance,which is the basis for the management of airspace under the operating environment of high-density aircraft.As one of the major aviation nations in the world,in the face of the increasing number of civil aviation aircraft and the increase in flight flow,research on the technology of four-dimensional aircraft trajectory prediction is urgent.This paper introduces the significance and development of 4D trajectory prediction technology,the current research status both at home and abroad,and then summarizes some of the advantages and disadvantages of China's 4D trajectory prediction research and the technology to be further studied.
