Abstract
Since ground penetrating radar (GPR) is a portable device, its battery life is very important for finishing scanning problematic area at the first time. Thus, importance of energy-efficient algorithm of GPR that we developed previously becomes more evident. This paper aims to investigate the effect of radius of buried object and layer surface slope on energy efficiency of the developed energy-efficient algorithm of GPR via computer simulations. Simulation models having a layer with wavy rough surface and a buried object were separately created. Critical values of wavy rough surface slope and buried object radius that guarantee energy efficiency at GPR scanning were determined. It was found that critical values changed with relative dielectric constant, conductivity, and depth of the layer or buried object. The simulations were carried out using 2D-finite difference time domain (FDTD) method in Matlab environment. Transverse electric mode and perfectly matched layer were applied while using 2D-FDTD approach.
