Fault Diagnosis of ERT System Based on Choquet Integral

Considerations on the Electrode-Spacing-to-Electrode-Diameter Ratio in Electrical Resistivity Tomography (ERT): An Operational Approach

“…4 and Fig. 5, for each of the four tested inter-electrode distances "𝑎" (the four panels) and for each electrode type expressed as its 𝑎 𝜑 ⁄ value (different colours), the acquired 𝜌 𝑎 values are shown as function of the pseudo-depth [11] for the DD and PD arrays, respectively. The global legend above Fig.…”

“…In Fig. 2c the 806 apparent resistivity acquisitions for the DD-ERT with "𝑎" = 10 𝑐𝑚 are shown, and each line of dots represents the so-called pseudo-depth as in [11]. It is important to remember here, in fact, that an increase in the electrode spacing "𝑎" allows to reach a higher depth of investigation.…”

Furthermore, ERT is commonly used also for the reconstruction of the resistivity of other objects instead of the soil.…”
