Decomposition of the time reversal operator (DORT), a recently applied time reversal method to transmission lines, has shown to be effective in detecting and locating soft faults in complex wire networks. In this paper, we will conduct a statistical study investigating the influence of several parameters, namely the number of testing ports in addition to noise, on the performance of DORT technique after having proposed a suitable fault location criterion. Notably, this would allow a closer inspection of the method’s practicability for future implementation in real-life networks.
