A Method to Check ADS-B Message Based on Direction-finder Antenna

摘要

Automatic Dependent Surveillance Broadcast (ADS-B) is a recommended advanced surveillance technology in Future Air Navigation Systems by ICAO. ADS-B is the technology that can provide the surveillance capabilities based on GNSS and ground-air data link. Because the frequency and the coding mechanism are in public, it is easy to be disturbed and deceived. The essay analyzed some traditional methods to check ADS-B information, and introduced a new checking method based on Direction-finder Antenna that fused radio character and Kalman Filter algorithm together. It can identify the false ADS-B message efficiently.
