Simulation Performance Analysis of Airborne Data Bus Under Interference Environment

The airborne data bus technology is one of the most core technologies in the world's advanced aircraft. With the development of digital technology and the application of computers, more and more avionics systems have been digitized, and the airborne data bus technology has also been developed at a high speed.Common airborne bus such as 429 airborne bus and 1553B airborne bus, has been widely used in the field of aviation communication because of its high reliability, fast speed, low design cost, strong compatibility and other advantages. At present, airborne bus communication mainly transmits signals in wired mode, which ensures the stability and security of signal transmission to a certain extent. With the development of 5G and cloud communication technology, airborne bus transmission technology is expected to be wireless in the future. At that time, the airborne bus in the wireless environment was inevitably affected and interfered by other airborne equipment or space electromagnetic radiation. Therefore, in this paper, the 429 airborne bus and 1553B airborne bus are taken as the research objects. The Monte Carlo simulation platform for underlying signal transmission is established, and the anti-jamming ability of two common airborne buses is analyzed. Systematical research on the anti-jamming ability of airborne bus is of great significance for promoting the wider application and development of airborne bus technology.
