Problems solved by technology

[0004]At present, the receiving antenna of the conventional ADS-B ground base station only uses the ADS-B IN omnidirectional antenna, and does not have the function of checking and judging anti-false signals, which is easily affected by The spoofing interference of artificially malicious (radio enthusiasts or criminals) ADS-B false signals seriously affects the normal order and operational safety of military and civil aviation air transportation

Embodiment Construction

[0012] The present invention will be described in detail below.

[0013] The invention includes ADS-B host (1), anti-false target processing host (2), anti-false target direction-finding antenna (3), BD / GPS antenna (4), ADS-B receiving antenna (5), PC ( option) (6), BD / GPS satellite (7), aircraft (8).

[0014] Compare the real spatial position of the ADS-B transmitter with the spatial position information in the ADS-B message it sends to determine its authenticity: if they are consistent, it is real and effective ADS-B information; if they are inconsistent, It is illegal ADS-B information, that is, a spoofing attack.

[0015] 1) The malicious cheater will usually be somewhere on the ground P r , compile one / set of false 3D position information P 1…… P s , artificially modulate a false and illegal ADS-B message, and use the transmission source to transmit it through the ground-air data link channel; 2) At present, the standard ADS-B ground base station receives the false A...

Abstract

The invention relates to an ADS-B (automatic dependent surveillance - broadcast) autonomous anti-false object spoofing method. The ADS-B is based on a GNSS (global navigation satellite system), ground-air data links and other advanced techniques, and is a novel ground-air surveillance system which is being globally popularized by ICAO (international civil aviation organization). Because of the opening and sharing characteristics of working frequency, signal format and communication protocol of the ADS-B, the application of the system will be easily subject to artificial malicious spoofing and attack by wireless amateurs or illegal persons, a false target is formed, the management of ATC (air traffic control) areas is disordered, the normal aviation flight order is seriously disturbed, and the severe hidden hazards on safety are caused. The system comprises an ADS-B ground base station host, an anti-false target processing auxiliary machine, an BD / GPS (Beidou global positioning system) antenna, an ADS-B receiving antenna, an anti-false target direction measuring antenna, a PC (personal computer) (optional), an BD / GPS satellite, and an aircraft.

Description

technical field [0001] The invention relates to a ground-air monitoring application technology of military and civilian aviation control on aircraft targets, which is a system device for ground-air monitoring using the information emitted by the aircraft targets themselves. Background technique [0002] Automatic Dependent Surveillance-Broadcast (ADS-B) integrates advanced technologies such as global navigation satellite system GNSS (GPS / BD / GLONASS / GALLILEO) and ground-air data link (1090 ES / VDL MODE 4 / UAT). A new ground-to-air surveillance system being rolled out around the world. This technology was born in the mid-to-late 1990s, and was gradually popularized and applied in military and civil aviation and air transportation fields around the world at the beginning of this century. In recent years, the commercialization of ADS-B system and its equipment has greatly accelerated. [0003] The ADS-B system (mainly refers to the ADS-B ground base station) receives various RF r...
