A Study of the Electromagnetic Characteristics of the Signals from the Electric Trains of Taiwan's Railway system
Abstract
We collected electromagnetic responses near the tracks of the Taiwan Railway, in order to realize the possible influences from these artificial electromagnetic signals from the electric train. We identify the electric and magnetic signals from different type of electric trains. The power spectrum analysis shows that the noise frequencies of the train signals extend from 10-1 to over several hundred Hz. We also discovered that different trains exhibit unique characteristics in their electromagnetic signals. Hence it would be able to pinpoint the signals to their train sources. Since these signals have stationary sources and high power level compared to the background, they may have the potential to serve as the artificial sources for the electromagnetic surveys. We would work further on the possibility to use these signals from the electric trains and high speed railroads as active sources for subsurface explorations in the future works.
