Method for compensating for propagation inhomogeneities for a temporal reflectometry signal

Abstract

A method for compensating for the propagation inhomogeneities in a time-domain reflectogram measured for a given cable comprises the following steps, executed in an iterative manner: injecting a test signal into the cable, measuring the reflection of the test signal to form a time-domain reflectogram, identifying at least a time portion of the time-domain reflectogram comprising at least one amplitude peak corresponding to a propagation inhomogeneity, subtracting the identified time portion of the reflectogram, divided by the signal reflection coefficient at the injection point, from the test signal, and replacing the test signal with the result of the subtraction.
