Case study: prediction of RFI effects of electrified railways onaeronautical radio navigation stations

摘要

The case is that an electrified railway line is 300 meters awayacross an airport runway. The paper studies both of active and passiveradio frequency interference caused by the electrified railways toaeronautical radio navigation stations, especially to instrument landingsystems (ILS). The EMC prediction model has been built. The predictionresults agreed with the results of the actual flying check test
