The purpose of this guide is to describe the measurement principles of the electrical properties of naturally occurring solid materials, although it will also serve as a guide for the measurement of any solid material.
Document needed for ground plane assessment for locating antennas; formation mapping to obtain geological information; assessment of ore-grade quality, moisture content, salinity; propagation prediction and studies; aquifer studies for water search, nuclear waste disposal, dam location; ground-penetrating radar research; prospectin.
Revision Standard – Superseded. ” The electromagnetic properties of the earth play an important role in the design and implementationof radio communications systems, geophysical prospecting instruments, and subsurface mapping techniques.Measurement techniques include dc resistivity, surface impedance, propagation studies, wave tilt methods,probe impedance methods, mutual impedance methods, transient methods, time domain reflectometry, groundprobing radar, laboratory-based techniques, and free-space reflection measurements. The separation distancebetween the probes and the wavelength of the radiation both affect the volume of earth material measured.This guide provides a summary of current measurement techniques and, where appropriate, inversion methodsfor determining the conductivity and the relative permittivity of the volume under investigation.”
