摘　　要：提出了一种采用ADS-B的冲突飞机选择算法,满足未来空域复杂交通态势对自由飞行的需求。算法利用ADS-B提供丰富航行信息及高速更新率等特点,在本机周围40～100nmile范围内,选择出有可能发生冲突的飞机。运用Matlab进行功能仿真,并通过Monte-Carlo方法分析其性能,结果表明算法在排除无威胁飞机方面性能良好,选择效果明显。该算法可以作为飞机冲突概率预测的预处理算法,对保证自由飞行下的飞行安全有着积极的意义。An algorithm based on ADS-B was proposed to meet the demand of collision avoidance for the complicated traffic situation of Free Flight in the future. The algorithm selected the potential conflict aircrafts within 40 - 100 nmile radius, which took advantages of abundant information and high updating rate of ADSB. Function simulation was carried out by using Matlab, and Monte-Carlo method was used to analyze the efficiency of this algorithm. The results show that the algorithm has a good performance in selecting conflict aircrafts from secure aircrafts. The algorithm can be used as the pre-processing of the conflict probability prediction algorithm, which is helpful to the safety of Free Flight in the future.
