The radiation characteristics of the pantograph-catenary arc and its influence on the airport glide beacon are studied.A typical line of electric multiple units is chosen in the study.According to the standard of CISPR16-1,the electromagnetic radiation of the pantograph-catenary arc at the neutral section and the general point is measured using the electro magnetic interference receiver,and its characteristics in the spectrum range of the glide beacon are obtained.Based on the wave propagation theory,the im...
