The use of GPR polarization parameters for the control of plane-layered media condition

Abstract

The possibilities of joint application of ultra-wideband GPR pulses and an algorithm for processing the polarization state of electromagnetic waves reflected by a plane-layered medium for solving the problem of the thickness measure of plane layered media are considered. This method differs from previously known approaches primarily by using ultra-wideband pulse signals in conjunction with specialized antenna units of modern GPR. Computational experiments of verification of the used models and experimental measurements of the influence of the orientation of the antenna units of the GPR relative to the boundaries of the sensed medium are carried out. The obtained results can be applied in optimizing the characteristics and design of GPR, as well as for interpreting road survey data.
