引言随着雷达管制和RVSM的实施,航管监视雷达对监视空中飞行目标起着越来越重要的作用,实现管制区域内的多重雷达覆盖也是发展趋势。在维护雷达设备过程中,面对雷神雷达一次方位系统故障,如何准确地分析、判断故障点,采取一切必要措施快速恢复一、二次雷达设备正常工作,对于确保空中交通管理安全有着重要的意义。笔 INTRODUCTION With the implementation of radar control and RVSM, the air traffic surveillance radar has played an increasingly important role in the surveillance of airborne targets. It is also a trend to achieve multiple radar coverage within the controlled area. In the process of maintaining radar equipment, the Rayleigh radar in the face of a fault location system, how to accurately analyze and determine the point of failure, to take all necessary measures to quickly restore the first and second radar equipment to work properly, to ensure the safety of air traffic management is of great significance . pen
