Chaos time-domain reflectometry for distributed diagnosis of complex topology wired networks

Abstract : A new reflectometry-based wire diagnosis method using chaotic signals is presented. It shows excellent potential for the diagnosis of live wires (i.e. during their operational usage) and complex topology networks. The use of chaotic signals for distributed diagnosis and the detection of defects in wires is investigated. Chaos time-domain Reflectometry (CTDR) using low auto-correlation sidelobes signals, shows high performances in very noisy environment: the detection and location of hard defects are possible, even if several reflectometers inject their signals concurrently with the diagnosis and the normal operation of the cable. This enables using CTDR for distributed diagnosis of complex topology networks.
