Abstract: Based on the characteristics of the satellite-based automatic dependent surveillance (ADS)system and radar, the model of ADS and radar data fusion system are studied and the registration algorithm in the traditional Earth-Centered Earth-Fixed (ECEF)coordinate system is presented.In the meantime, according to the characteristics of ADS data, the registration algorithms in Geodetic coordinate system and radar polar coordinate system are further proposed.Simulated and real-life data are used to evaluate the performance of the proposed algorithms and comparisons are made.The effect way to better use the above algorithms in practical situations is introduced.

Key words: air traffic control (ATC), registration, automatic dependent surveillance (ADS), radar
