Time reversal for soft faults diagnosis in wire networks

Abstract : Time-reversal (TR) invariance of the wave equation in lossless transmission line (TL) is here introduced as an improvement for fault-detection techniques in wire networks. This new approach is applied to re°ectometry in wire diagnosis. To test the e±ciency of this method, the reverse time algorithm simulated with FDTD (Finite Di®erence Time Domain) is developed in a one dimension space. It uses a new signal processing and an adapted signal to the wire under test for diagnosing the fault in the wire. In addition, the interest of the convolution product between the incident signal and the output signal from this reverse time method will be also shown and applied in this paper. Through numerical simulations and experimental results measured on coaxial cable, the bene-ts of this method have been illustrated.
