REFLECTOMETRY METHOD FOR IDENTIFYING SOFT FAULTS AFFECTING A CABLE

The reflectometry method for identifying at least one fault affecting a cable at at least one point, comprises: a step for estimating a parameter characteristic of the propagation of a signal within the cable, which include the attenuation α(f), the phase factor (f), the reflection coefficient in(f)...

Zusammenfassung:The reflectometry method for identifying at least one fault affecting a cable at at least one point, comprises: a step for estimating a parameter characteristic of the propagation of a signal within the cable, which include the attenuation α(f), the phase factor (f), the reflection coefficient in(f) seen at the input of the cable from which is subtracted an estimate of the reflection coefficient in the absence of faults or a function, linear or non-linear, any of these parameters or a combination of parameters, the estimation being made as a function of the frequency of the signal based on a reflectogram of the signal, a step for transformation of the estimate of the parameter from the frequency domain into the time domain, a step for identification of the faults affecting the cable from the identification of the amplitude peaks of the estimate of the parameter transformed into the time domain.
