Abstract
A method and device for detecting faults in a transmission line by reflectometry, include the following steps: injecting into the transmission line a reference signal at an emission frequency f; collecting a reflected signal at a point on the transmission line; sampling the reflected signal at a sampling frequency f, the sampling frequency fbeing different from the emission frequency f; storing each point of the sampled signal at a memory address corresponding to an index assigned to the point of the sampled signal and according to a precomputed memory-address increment Δ, the memory-address increment Δ depending on the emission frequency f, on the sampling frequency f, on an over-sampling factor Ω and on a preset acquisition time Σ; repeating the storing step during the acquisition time Σ; and generating, from the points stored during the acquisition time, a recomposed signal able to be used to detect faults.
