摘要：
二次雷达是空中交通管制领域重要的监视设备，其工作性能的发挥与周围电磁环境密切相关。为保证二次雷达安全运行，需要对周围的场地环境进行分析和评估。首先，介绍电磁环境评估的一般方法；其次，分析基于电磁环境的二次雷达场地安全评估的流程；最后，以新疆乌鲁木齐机场新建二次雷达和拟建机场高速公路为例，通过在各个频点对高速公路产生的干扰场强进行测量，利用无源干扰和有源干扰对机场附近的电磁环境进行分析。结果表明：高速公路产生的峰值场强、平均值场强均不会影响该机场拟建空管二次雷达的正常运行。

Abstract: Secondary surveillance radar (SSR) is a kind of important surveillance equipment in the air traffic control field,and its working performance is closely related to the surrounding electromagnetic environment.In order to ensure the safe running of SSR,it is necessary to analyze and evaluate the surrounding environment.Firstly,the general method of electromagnetic environment assessment is introduced.Secondly,the process of safety assessment for secondary radar site based on electromagnetic environment is analyzed.Finally,taking the new SSR in Xinjiang Urumqi airport and proposed airport highway as examples,by measuring the interference field strength generated by the expressway at various frequency points,the electromagnetic environment near the airport is analyzed through passive interference and active disturbance.The results show that the peak field strength and the average field strength of the highway will not affect the normal operation of proposed air traffic control SSR.
Keywords: SSR;active interference;passive interference;electromagnetic assessment
