Water Detection Using Bi-Wires as Sensing Elements: Comparison Between Capacimetry-Based and Time-of-Flight-Based Techniques


It is known that bi-wires can be employed as passive distributed sensing elements (SEs), to accurately locate water infiltrations in soil, concrete materials, and so on, using the standard time-domain reflectometry instrumentation and proper signal processing. This paper examines the possibility of using the same kind of SEs with simpler techniques and… (More)
