A selection algorithm for conflict aircrafts and performance analysis based on ADS-B

A selection algorithm of conflict aircrafts based on ADS-B was proposed in this paper, which respectively execute angle selection and speed selection in a certain range around host aircraft and select the potential conflict ones effectively. Algorithm simulation results show that the selection algorithm had good performance in terms of excluding non-threatening aircraft from secure ones. As pre-process of conflict probability prediction algorithm, the results can be used to reduce the unnecessary waste of resources as well as the burden on the pilot, which must be helpful to the safety of free flight in the future.
