Using neural networks for calibration of time- domain reflectometry measurements
Time-domain reflectometry (TDR) is an electromagnetic technique for measurements of water and solute transport in soils. The relationship between the TDR-measured dielectric constant (Ka) and bulk soil electrical conductivity (cra) to water content (8W) and solute concentration is difficult to describe physically due to the complex dielectric response of wet soil. This has led to the developmen...
متن کاملTime Domain Reflectometry: Temperature- dependent Measurements of Soil Dielectric Permittivity
The purpose of this study is to determine the temperature influence on the soil bulk dielectric permittivity, ε b, calculated from the measurement of the electromagnetic wave velocity of propagation along the parallel waveguide in a TDR probe, i.e. a probe working in Time Domain Reflectometry technique. The experimental evidence shows that the existing models do not completely describe the temp...

متن کاملUxo Discrimination Using Time Domain Electromagnetic Induction
An explosive ordnance is a munition that is either launched or fired with the intent of detonation at a specified target. An unexploded ordnance (UXO) is an explosive ordnance that, due to some malfunction, remains undetonated. As a result, the ordnance can be found at the ground surface, partially buried, or buried at a depth of up to 8 m beneath the surface. Practical and cost-effective strat...
متن کاملCable Diagnostics with On-voltage Time Domain Reflectometry
In this paper a diagnostics technique is presented for localization of degraded regions along an XLPE insulated power cable. The diagnostics would help to develop a strategy for condition based maintenance of old XLPE power cables. A design of the diagnostics system and results of measurements performed on two power cables are presented. The measurements data is processed in order to localize t...
