Abstract
A reflectometry system for the analysis of faults in a transmission line into which a complex signal, generated then modulated, has been injected, includes a means for measuring the modulated complex signal propagating in the transmission line, a demodulator of the measured signal designed to produce a demodulated complex signal, a complex correlator configured for correlating the demodulated complex signal with a copy of the generated complex signal, in order to produce a first time-domain reflectogram corresponding to the real part of the complex correlation and a second time-domain reflectogram corresponding to the imaginary part of the complex correlation, a module for joint analysis of the first time-domain reflectogram and of the second time-domain reflectogram for identifying the presence of faults in the transmission line.
