航管监视系统现状分析

Analysis on the ATC Monitoring System

本文叙述了随着卫星和计算机网络技术在空管系统的应用,目前空管系统主要采取一次雷达、二次雷达、ADS-B,三种监视手段共用,具体介绍一次监视雷达(PSR)、二次监视雷达(SSR)、广播式自动相关监视(ADS-B)的基本原理和应用。并对未来监视技术进行了展望,未来将建立若干地面卫星站,实时掌握飞行数据。

As satellite and computer network technology more and more frequently used, we described the current air traffic control system, which including primary radar, secondary radar, and ADS-B in this paper. And we mainly introduced the basic principles and applications of the primary surveillance radar（PSR）, secondary surveillance radar（SSR）, and automatic broadcast dependent surveillance. The future trends of surveillance technology are to establish more satellite ground stations to obtain real-time flight data.
