METHOD FOR DETERMINATION OF ELECTROPHYSICAL PROPERTIES OF GROUND DEPOSITS BY MICROWAVE METHOD

摘要

Microwave method for controlling the humidity of solid materials in the Brewster angle, comprising indoor test material in high-frequency electromagnetic field with a subsequent registration of changes of parameters characterizing the high-frequency radiation, characterized in that the processing of the measured parameter characterizing the high-frequency radiation, is to remove signal feedthrough and application signal to the modified Hilbert transform to construct the envelope to the courses of the received signal, allowing opred elit position of the visible boundaries of soil layers; signal amplitude at these points and coefficients of attenuation of electromagnetic radiation within the individual ground layers, then based on sootnosheniiiopredelyaetsya refractive index (permittivity) of ground layer varying degrees of humidity on the basis of the two surveys, and using the ratio determined by conductivity, refractive index somewhere precoat layer at various humidities, ε - dielectric constant of the precoat layer, σ - conductivity precoat layer - visible layer thickness for p ase humidities, A = E'E, (E) E '- the amplitude of the signal reflected by the upper surface of the precoat layer by varying humidity, μ- magnetic constant, ω - central angular frequency radiation ,, c - the speed of electromagnetic radiation in vacuum, p- electromagnetic radiation attenuation coefficient in the soil layer.
