Abstract
A method for characterizing a fault affecting a cable in which a reference signal s of limited time support is injected and a measurement r of the reflection of the reference signal s in the cable is taken, comprises the following steps: identifying a section of the measurement r corresponding to a fault, this measurement section being called the signature of the fault; generating a modified reference signal s', of parameterizable amplitude, equal to the sum of the reference signal s and of the reference signal s inverted and delayed by a parameterizable delay; determining conjointly the values of the parameterizable delay and of the parameterizable amplitude that minimize the error between the modified reference signal s′ and the signature of the fault; and deducing therefrom an estimation of the length of the fault from the determined value of the delay.
