随着低空空域的开放和通用航空的发展,低空空域流量大幅增加,致使飞机飞行冲突事件呈多发态势。为了解决低空冲突问题,基于广播式自动相关监视(ADS-B)信息的避让算法,首先利用相对运动关系对本机周围的飞行状况进行分析,排除不存在危险冲突的航空器;然后针对危险接近的航空器,提出调整速度和改变航向两种避让策略;最后利用Matlab软件,对两种避让算法进行仿真分析。结果表明:算法正确有效,能够快速辨别飞行冲突,并给出合理的避让策略;调整航向的避让算法,其有效性优于调整速度的避让算法,但在实际飞行中,由于调整速度的避让方法更易操作且节约成本,应优先选择调整速度的避让方案。
With the opening up of low-altitude airspace and the development of general aviation, the traffic volume in low-altitude airspace increased sharply, causing frequent occurrences of aircraft flight conflicts. In order to solve the problem of low-altitude conflict, the algorithm of avoiding information based on ADS-B is firstly to analyze the flight conditions around the aircraft by using the relative motion relationship and to exclude the aircraft without any dangerous conflict. Then, , Proposed to adjust the speed and change the heading of two avoidance strategies; Finally, the use of Matlab software, two avoidance algorithms for simulation analysis. The results show that the algorithm is correct and effective, can quickly identify the flight conflict and gives a reasonable avoidance strategy; and the adjustment of the heading avoidance algorithm is more effective than the adjustment speed avoidance algorithm. However, in actual flight, due to the adjustment of the speed avoidance method Easier to operate and cost savings, priority should be given to adjust the speed of avoidance programs.
