摘　　要：通过分析飞机飞行过程中的航迹误差,提出了估计飞行冲突可能性大小的概率型中期冲突探测的思想。针对我国民航航路由多个航路段组成的特点,提出了改进的中期冲突探测算法。该方法参考飞行过程中的最小间距点,找出两飞机在整个预测时间内的5个极小间距点作为航迹误差的累积过程,从而更精确地描述了两机相遇几何中的联合航迹误差。最后实例仿真计算表明,该算法完全能满足空中交通管制对算法实时性的要求,可以应用于实际的空中交通管制系统中。After analyzing the route error of flight,an idea of using approximate analytical approach to estimate conflict probability between airplanes was proposed.To adapt for multi-route-segement in China,a new improved mid-term conflict detection algorithm was presented.This method considered the minimum distance point in flight,found out the five minimum distance points in the prediction time as the cumulative process of route error,and then the combined route error of two airplanes encounting could be more accurately described.The results of the simulation indicate analytical approach can meet the real-time requirements of air traffic control,and can be applied to the actual air traffic control system.
