Abstract :
The invariance of the wave equation under time-reversal (TR) in a lossless transmission line is exploited for the detection and localisation of soft faults in a wire network. An original TR signal processing is exposed and evaluated on numerical examples. This new wiring diagnosis´s effectiveness is discussed and pointed out.
