The estimation of buried empty cylindrical tubes characteristics using GPR

Abstract

This paper proposes a method to estimate three parameters: the radius, the depth of buried empty cylindrical tubes and the dielectric constant of the surrounding medium, by Ground Penetration Radar (GPR). These parameters are detected and characterized by radargrams. Those radargrams contain a parabolic shape that indicates the presence of target. This is can be achieved through two major phases: the processing stage of the electromagnetic (EM) signals which are received by the GPR. This stage is followed by another one which is the fitting curve of the parabolic shape appeared in the radargram. Finally, the results clearly indicate that this method is perfectly able to estimate the depth within 1.66%, mean average error rate and the relative permittivity of the emulsion of 3.41% and that the radius of 29.52%, whish justify and validates the model used.
