A method for detecting soft faults in a transmission line includes the following steps: acquiring a measurement, called time-domain reflectogram, of a signal characteristic of the reflection of a reference signal previously injected into the line, determining the difference between the time-domain reflectogram and a time-domain reflectogram measured previously for the same line or an identical line of similar characteristics, in order to obtain a corrected time-domain reflectogram, applying a plurality of independent transformations to the corrected time-domain reflectogram in order to obtain a plurality of independent transformed reflectograms, converting the transformed reflectograms into a plurality of mutually independent probabilities of occurrence of a fault, applying a data merging method to the probabilities of occurrence of a fault to deduce therefrom a unified value of the probability of occurrence of a fault.
