TCAS/ADS-B Integrated Surveillance and Collision Avoidance System

摘要

The air collision avoidance system is an important measure to ensure the flight safety. One of the sticking point of collision avoidance is surveillance precisely and reliably. So, it is necessary to develop an independent and reliable air-air surveillance system. A TCAS/ADS-B integrated surveillance and collision avoidance system was proposed in this paper. This system is based on the TCAS original collision avoidance function, and integrated with ADS-B broadcasting information. Using the present statistical model and data fusion algorithm, the integrated system can get optimal fusion track estimate. The simulation results show that this integrated system can improve TCAS tracking accuracy, improve the surveillance precision and collision avoidance reliability.
