Abstract
It is very important to understand the electromagnetic characteristics of underground media in GPR (Ground Penetrating Radar) survey. Depending on the electrical characteristics of the underground medium, the energy of the electromagnetic wave becomes relatively small, and reflection from the interface may become difficult. In this study, electrical characteristics of sandy soils under various (loose and dense) conditions were analyzed. As a result, In dry sand is the dielectric constant increased as the relative density increased, and the dielectric constant and electrical conductivity increased as the moisture content of the sand increased.
