民航进口在役空管二次雷达维修维护实践

Maintenance practice of imported in-service ATC secondary radar for civil aviation

为了对国内民航空管系统在运行的140多套雷达设备天线与天线座专项巡检提供技术建议,更科学地检测评估雷达性能。以空管局贵阳磊庄雷达站INDRA二次雷达目标方位偏移现象为例,围绕空管单脉冲二次雷达目标角度信息因素,分析研究会造成方位故障的原因,详细阐述故障排查解决的过程,最终有效恢复了雷达正常运行。

In order to provide technical suggestions for the special inspection of antenna and antenna base of more than 140 sets of radar equipment in operation of domestic civil aviation air traffic control system,and more scientifically detect and evaluate radar performance.Taking the Indra secondary radar target azimuth offset phenomenon of Guiyang leizhuang radar station of air traffic control bureau as an example,focusing on the target angle information factors of air traffic control monopulse secondary radar,the causes of azimuth fault are analyzed and studied,the troubleshooting process is described in detail,and finally the normal operation of radar is effectively restored.
