Study on the Influence of signboard on Spatial Signal of GlidePath

With the rapid development of civil aviation industry, in order to improve airport capacity, more and more large hub airports build new runways and adopt multi-runway operation, which will cause the taxiway connecting the outer runway to cross Glidepath site protection area of the inner runway. At the same time, the signboard on both sides of the taxiway will be located in the protection area of the GlidePath, which does not meet the requirements of GB6364-2013 and MH/T4003.1-2021. The installation of the signboard may affect the spatial signal of the GlidePath and further affect the aviation operation safety. To solve these problems, this paper analyzes and demonstrates the influence of signboard on spatial signal of GlidePath from multipath interference and radiation interference, which provides theoretical support for construction of signboard and has important engineering value.
