For More Reliable Aviation Navigation: Improving the Existing Assessment of Airport Electromagnetic Environment

Abstract

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.
