Summary:
We develop some aspects of the electromagnetic theory regarding the application of the ground-penetrating radar (GPR), namely, a model for the composite dielectric constant, the amplitude variations with offset (AVO), the concept of exploding reflector and Backus averaging to obtain the properties of finely-layered media. The electromagnetic properties are obtained by using a generalization of the Hanai-Bruggeman (HB) equation. The HB exponent (1/3 for spherical particles) is used as a fitting parameter for a sand-clay mixture saturated with water.
