【Abstract】: In order to improve the utilization efficiency and operational stability of Mode S monitoring data in air traffic control automation system, an algorithm model based on alpha-bet-gama trace filtering algorithm and related Mode S monitoring data processing and analysis is proposed. The analysis of key data items in the message is studied, and the algorithm model is adopted to monitor the quality of data and the flight plane projection. According to the algorithm studied, an air traffic control Mode S monitoring data quality analysis system is designed, which supports the access of multiple monitoring source channels, can analyze the data quality in real time, statistics related error rate, and has the functions of truly reflecting the movement of the target trail. The experimental results show that: The engineering of this system is more concise, has good stability and robustness, can assist technical maintenance personnel to find the abnormality of Mode S monitoring data source in time, as well as provides a feasible and effective monitoring method for promoting the wide application of Mode S monitoring data, suggesting a certain application value in air traffic control units or local towers.
