摘要
一次雷达是空中交通领域重要的监视设备,是国防和民航空管的核心装备。周围的地形和设施可能会影响一次雷达性能的正常发挥,为保证航空安全,需要对雷达场地周围的地形和设施进行评估分析。以东部机场规划建设磁悬浮铁路为例,分析评估了磁悬浮铁路对机场空管一次雷达的影响。结果表明:磁悬浮列车牵引和制动时,产生的峰值场强、准峰值和平均值场强不会影响该机场空管一次雷达的正常运行;磁悬浮铁路在有列车经过时,也不会影响空管一次雷达的正常运行。
Primary Surveillance Radar（PSR） is of significant importance to the air traffic control for its important surveillance information. The surrounding terrain and facilities are the main factors that affect the PSR performance. To ensure aviation safety, it is necessary to evaluate the influences of terrain and facilities around the radar site. Take an airport in the eastern China region as an example, near which a magnetic levi- tation railroad is planning to construct. The analysis and evaluation of the railway influence on the airport air traffic control primary radar are made. The results indicate that the peak magnetic field strength and the qua- si-peak strength and the average field strength created when the maglev train tracts and brakes will not affect the operation of the ATC primary radars. Also, when maglev railway train passing by, the PSR operation is able to maintain its normal performance.
