Multi-path interference analysis and simulation of secondary surveillance radar for civil aviation ATC

摘要

For target interference phenomenon of civil aviation ATC (Air Traffic Control) secondary surveillance radar, this paper takes the multipath interference of passive interference factors as the breakthrough point. Based on the two analysis angles- the multipath signal in the same vertical plane and the multipath signal of two horizontal angle, the paper analyses the mechanism of ATC secondary surveillance radar multipath interference, mathematical model and the prevention measures; At the same time, combined with the actual radar operation situation, the paper takes MATLAB dynamic simulation tool to analyze and study the radar target interference caused by multipath.
