Radar / ADS-B data fusion architecture for experimentation purpose

This paper describes data fusion architecture for air traffic control applications based on radar plots and ADS-B reports. ADS-B reports help to enhance accuracy of system tracks and radar plots provide track continuity over mixed ADS-B and radar coverage area. The chosen architecture makes use of all available measurements (radar data being synchronized according to revolution time period, while ADS data are taken into account in an asynchronous way) to produce an unique track for each aircraft, making global optimal data association and correcting sensor biases. The proposed architecture has been designed for experimentation purpose: it aims to prepare a mature model based on operational feedback. Simulations are conducted on live recording and highlight the benefits of the architecture over wide area
