abstract="In order to accurately evaluate monitoring information quality and provide decision-making reference for air traffic control (ATC) so as to prevent accidents, an information quality evaluation system was developed. Firstly, seven indices were chosen from three perspectives of integrity, accuracy and correctness, and they included target tracking integrity, target parameter integrity, position accuracy, velocity accuracy, heading accuracy, parameter correctness, probability value of true target. Secondly, with minimum total deviation as an aim, weights of these indices were determined by employing EAHP and entropy before evaluating value of monitoring information quality was obtained through weighted sum. Then, corresponding level of estimated values were decided through comparison with evaluating standards set by experts. Finally, simulated experiment was conducted with nine target trajectories in one period of a sector in North China as an instance. The results show that the evaluating results of the nine target trajectories are consistent with experts' analyses. The proposed evaluating system provides an effective and reliable approach to assess monitoring information, which can improve ACT safety. © 2022, Editorial Department of China Safety Science Journal.
