Abstract	La réflectométrie est une méthode couramment utilisée pour déterminer l’état électrique de câbles et de lignes. Cette méthode fournit des informations pour la détection, la localisation et la caractérisation de défauts électriques. Le CEA LIST travaille sur l’implémentation de cette méthode pour le diagnostic de réseaux filaires de topologie complexe, pour des applications embarquées ou de diagnostic en ligne. Les domaines d’application concernent les télécommunications, l’automobile et les transports, la distribution d’énergie, etc.Cet article présente un nouveau modèle théorique pour la simulation rapide et précise de signaux de réflectométrie appliquée à tout type de réseau filaire. Basée sur la théorie de la propagation RF, ce modèle fournit des formules explicites pour simuler la réflectométrie dans les domaines temporel (TDR) et fréquentiel (FDR), explique les phénomènes et permet une meilleure compréhension de ces signaux en rapport avec la topologie du réseau.Reflectometry is a well known method widely used to monitor the health of lines and wired networks. This method provides information for the detection, localization and characterization of electrical defects in networks. CEA LIST works on the development and the application of this method for the diagnosis of wired networks of complex topology, targeting embedded systems. Application domains range from telecommunication to automotive and transport, energy distribution, etc.This paper presents a new theoretical model for the precise numerical simulation of reflectometry signals applied to any kind of wired network. Based on standard microwave propagation theory, this model provides simple explicit formulas for both time domain (TDR) and frequency domain (FDR) reflectometry, and is helpful to better understand and explain measurement results in relation with the network’s topology.
