Simulation study of ground penetrating radar operation with an antenna array

Abstract

Ground Penetrating Radar (GPR) is a geophysical technique based on the emission and reception of high-frequency electromagnetic waves, used to explore and map underground structures. The effectiveness of GPR is directly conditioned by the choice of the antenna, each offering specific properties that impact the accuracy of the information obtained. This work presents a simulation study of the operation of GPR radar with an antenna array as in the Reflexw software. Different models were carried out to evaluate the detection of objects of various shapes, sizes and natures, buried in various mediums. The results obtained showed the effectiveness of the antenna in most of the cases studied. However, in certain mediums with high conductivity, the rapid attenuation of GPR waves led to non-detection of objects.
