Abstract

This paper presents the investigation of antenna step and aperture size for an ultra-wideband (UWB) ground penetrating radar (GPR) with a linear array. The procedure includes the optimization of receiving array, verification of optimization results by EM simulation and experimental measurement for both surface and subsurface imaging. The imaging algorithm used for the evaluation combines the focusing of the array and the synthetic aperture radar technique in the mechanical scan direction.
