Résumé / Abstract
The integration of new technologies of communication, command-control or information transmission in railway vehicles requires a good knowledge of the electromagnetic (EM) environment in order to ensure the immunity of such systems in their operating transport environment. Consequently, it is important to carry out precise EM environment characterizations specific to the system that is to be integrated and need to be protected before applying the immunity tests that reproduce the measured EM noise conditions. This paper presents some of the treatments we have developed in order to extract well-focused and representative features from signals measured on board moving trains.
