Abstract
The electromagnetic environment in airport is very complex. glide-slope localizer and localizer are part of the Instrument Landing System. They cooperate with the airborne receiver to provide space guidance for the aircraft during the approach and landing process. The End-around Taxiway Screen built at the end of the airport runway will cause interference to the electromagnetic environment of the airport and have a certain impact on the aircraft approach and landing process. In this paper, the model of glide-slope localizer and localizer antenna array and the model of visual shield are established. The coupling effect of End-around Taxiway Screen (EAT Screen) and localizer antenna array is analyzed by image method. The hybrid simulation method of finite element and bouncing ray method is used to improve the simulation efficiency, which provides technical methods for the research of civil aviation electromagnetic compatibility and can provide support for the planning and construction of End-Around Taxiway Screen.
