METHOD FOR ANALYSING A CABLE, INVOLVING A PROCESSING OPERATION AMPLIFYING THE SIGNATURE OF A SOFT FAULT

A method for analyzing a cable into which a reference signal s(t) of bounded temporal support is injected comprises the following steps: acquiring a measurement signal r(t) characteristic of the measurement of the reflection of the reference signal s in the cable, identifying and selecting at least...

Zusammenfassung:A method for analyzing a cable into which a reference signal s(t) of bounded temporal support is injected comprises the following steps: acquiring a measurement signal r(t) characteristic of the measurement of the reflection of the reference signal s in the cable, identifying and selecting at least one point of the measurement signal r corresponding to when the signal crosses a zero value, generating, over a time interval centered around the at least one point with abscissa t0, and a modified signal z(t) with the aid of the following relation z(t0+t)=r(t0+t)−r(t0−t).
