Abstract

In the pursuit of comprehensively assessing the radiation emission characteristics of the balise transmission module (BTM) antenna within diverse train environments, this paper puts forward a novel approach grounded in similarity theory. Herein, the ideal radiation emission field distribution of a single BTM antenna serves as the reference two-dimensional dataset. The radiation emission field distribution specific to a given train environment is adopted as the input data. By calculating the similarity coefficients, the extent of influence exerted by different train settings on the radiation emission traits of BTM antennas can be accurately gauged. In addition, 13 representative train environments have been meticulously measured and evaluated. The results reveal that the mean square error (MSE) of this evaluation method is less than 0.011. This compellingly demonstrates the effectiveness of the method's predictive capabilities. In light of the above-mentioned theoretical postulations and practical exigencies, the proposed method empowers us to effectively evaluate the impact of a particular environment on the radiation characteristics of the BTM antenna even prior to the installation of BTM equipment.
