3. Conclusion

The concealment of electrical power networks through the use of underground cables, coupled with the ever-increasing extension of telecoms networks, can only make effective progress through the prevention of operational incidents. Reflectometry can therefore be a remedy on which many engineering teams are focusing their efforts to meet two major technical challenges. The first concerns the objectivity of a fault test. In the course of this article, we have shown, on a very simple configuration, that the location of an obstacle assimilated to a resistor can be ensured by three analysis methods: direct signal processing in the time domain, exclusive processing in the frequency domain, and then a combination of these two methods using pulse synthesis. The major advantage of pulse synthesis is that it improves the signal-to-noise ratio, but only if the noise is renewed randomly and in a stationary...
