基于微分对策的平行跑道独立运行冲突报警算法

为提高平行跑道运行时空中交通管制的安全和效率,通过跑道容量模型对首都机场的最大理论容量进行了分析,得出了两条平行跑道的最优运行方案。针对这种方案中的平行跑道独立运行安全保障问题,提出了一种基于微分对策的新报警方法,用它来代替传统的隔离带报警方法。这种方法假定入侵飞机是"追击者",另一架平行飞行的飞机是"躲避者",通过计算追击者的不安全区来达到报警目的。分析了最小水平安全间隔的变化。仿真试验证明,这种新的报警技术优于传统的隔离带报警方式。

Collision alerting algorithm based on differential games for independent approaches to parallel runways

The runway capacity model was used to show that independent approaches are possible at the capital airport in Beijing and that the model can be used to increase the safety and efficiency of approaches to parallel runways. Then, a novel design methodology based on differential games was used instead of the traditional no transgression zone as a means to alert cartrollers to potential conflicts. The new methodology considers the blunderer as a "pursuer" and the other aircraft as an "evader". With this technique, an alert is issued when the evader is within an unsafe boundary around the blunderer. The technique was used to analyze how the minimum safe longitudinal separation changes. Simulation shows that the new alerting technique is better than the traditional no transgression zone alerting criteria.
