High-speed trains close to airports emit electromagnetic radiation (EMR), which might interfere with the airport communication and navigation signals and create a safety hazard for the aircraft operation. Therefore, it is necessary to measure and evaluate the electromagnetic environment when building high-speed railway near the airport. In this paper, a new influence factor, train speed, is considered in the existing airport electromagnetic environment assessment system to make the evaluation result more reliable and real. We highlight the principles and results of the influence of train speed on the EMR from the high-speed train. Then, we present the corresponding train speed limit to mitigate the electromagnetic interference (EMI) of the nearby navigation station.

为了更可靠的航空导航：改进机场电磁环境的现有评估

靠近机场的高速列车会发出电磁辐射（EMR），这可能会干扰机场的通信和导航信号，并对飞机的运行造成安全隐患。因此，在机场附近建设高铁时，需要对电磁环境进行测量和评估。本文在现有机场电磁环境评估系统中考虑了一个新的影响因素列车速度，使评估结果更加可靠和真实。我们重点介绍了列车速度对高速列车 EMR 影响的原理和结果。然后，我们提出相应的列车限速以减轻附近导航站的电磁干扰（EMI）。
