摘 要: | 为了解决通航实际飞行中出现冲突情况复杂的问题,提出基于广播式自动相关监视(ADS-B)技术监视状态下的飞行冲突解脱算法。首先,将两机的冲突场景分成交叉、相向和追及冲突三种,利用相对运动调整航向和调节速度法,针对不同冲突场景给出相应可行的解脱模型。然后,基于空中交通管制防撞相关规定,建立不同解脱策略的选择标准,提升了算法的实际可行性。对不同解脱策略的解脱情况进行仿真和比较,表明该算法能够为具体的飞行冲突场景提供可行的解决方案。

Abstract: | To solve complex problems of conflict situations in general aviation flight, a flight collision resolution algorithm in ADS-B surveillance state is proposed. Above all, the conflict scenarios between two planes are divided into three classes, which are intersection collision, opposite collision and chase collision. And the correspondingly viable collision models for different conflict scenarios are deduced by using the heading adjustment method and speed adjustment method based on relative motion. Then the selection criteria for different release strategies are established based on the relevant provisions of the air traffic control to collision resolution, so the practical feasibility of the algorithm is enhanced. The simulation of different resolution strategies show that the algorithm is available to provide a viable solution for a specific flight conflict scenario. |
