Abstract :
An algorithm based on ADS-B was proposed to meet the demand of collision avoidance for the complicated traffic situation of Free Flight. The algorithm selected the potential conflict aircrafts within 40-100 nm radius, which took advantages of abundant information and high updating rate of ADS- B. Function simulation was carried out using MATLAB, then Monte-Carlo method was used to analysis 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 must be helpful to the safety of Free Flight in the future.
