摘要

针对民航ATC(空中交通管制)二次监视雷达的目标干扰现象，本文以被动干扰因素的多径干扰为切入点。基于同一垂直方向上的多径信号和两个水平方向上的多径信号两个分析角度，分析了空管二次监视雷达多径干扰产生的机理、数学模型和预防措施;同时，结合雷达实际工作情况，采用MATLAB动态仿真工具对雷达目标多径干扰进行了分析研究。

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

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.
