3. Reflectometry
Methods based on the principle of reflectometry are the best way to meet these requirements.
3.1 Principle
The principle of reflectometry is similar to that of radar: a wave is injected into a medium, and if it encounters a discontinuity during propagation, part of its energy is reflected back to the point of injection. By analyzing the reflected signals, we can deduce information about this discontinuity.
Today, reflectometry is used in a wide range of fields, from measuring moisture in soils, to characterizing strata in the earth's crust, measuring airways and detecting faults in cables.
The main drawback is that a tree topology network gives rise to complex signals...
