Abstract

The invention provides an ADS-B anti-interference anti-cheat ground single-station system. According to the system, on the basis of reserving all functions of an original ADS-B system, a monopulse anddifference angle measurement processing technology is adopted for performing accurate detection on the direction of a target source, and potential false cheat targets in most directions can be judged, so that the ADS-B anti-interference anti-cheat purpose is achieved; meanwhile, the system also has the characteristics of being small in size, light in weight, easy to erect, convenient in equipmentmaintenance, high in practicability, and small angle resolution of less than 0.6 degrees; and while angle measurement processing is performed by using monopulse and difference technologies, the judgment of the target geometric consistency and the target intention consistency is also fused, so that the ADS-B anti-interference anti-cheat effect can be more effectively realized.

Description

technical field [0001] The invention relates to the technical field of air traffic control data processing equipment, in particular to an ADS-B anti-interference and anti-spoofing ground single-station system. Background technique [0002] With the continuous construction and promotion of Automatic Dependent Surveillance-Broadcast (ADS-B) technology on a global scale, it has achieved remarkable technical and social benefits in the field of air transport, but the openness and sharing of ADS-B technology itself Automated monitoring architectures are also challenged by security issues such as being vulnerable to human falsehoods or misinformation. Since the ADS-B system broadcasts self-reporting of aircraft position and other information through the 1090ES ground-air / air-air data link, this open autonomous surveillance architecture is extremely vulnerable to hacker intrusion and false information deception, thus making The false data or erroneous location information that the ...
