基于雷达的多机冲突检测与调配

为防止空中飞机危险接近,保障飞行安全,提高管制员对飞行冲突的预见性和调配飞行冲突的能力,建立了基于雷达的坐标系,提出了预测多机飞行冲突的水平检测和预测冲突时间段的方法.研究表明：在水平投影面上,如果飞机Ai的保护区与飞机Aj的阴影交叉,将发生水平冲突;如果同时发生垂直冲突,那么飞机Ai和Aj将发生飞行冲突,需要在雷达监控下,通过改变航向、速度和飞行高度以避免飞行冲突.但若水平冲突和垂直冲突的时间段不交叉,则飞机Ai和Aj没有冲突,可以保持现有（平飞、下降或上升）状态飞行.仿真分析结果表明了检测和调配方法的正确性.

Flight Conflict Detection and Regulation between Aircraft Based on Radar

To avoid the air traffic collision,secure the flight safety and improve the air traffic controller's capability to foresee and deal with flight conflicts,a radar-based coordinate system was established,and the concept of "horizontal detection" to foresee multi-traffic flight conflicts was brought forward.Furthermore,a method to foresee the horizontal detection of multi-traffic flight conflicts and the time slice of conflicts was proposed.The research shows that if the protected zone of aircraft A_i is intercrossed with the shadow of aircraft A_j on a horizontal surface and there is a vertical conflict,a flight conflict between aircraft A_i and A_j will occur.Under this condition,it is advisable to adjust the aircraft heading and speed or alter the flight altitude to avoid the flight conflict with the help of a surveillance radar.However,if there is no intercross in the time slice of horizontal and vertical conflicts,no flight conflict will happen between aircraft A_iand A_j.Finally,a simulation analysis was made to test the validity of this method.
