RANGEL, D.; CARREON, D.; CERCA, M.  and  MENDEZ, E.. Valuation of ground penetrating radar for the record of structures in fluvio lacustrine soils. J. appl. res. technol [online]. 2003, vol.1, n.1, pp.85-93. ISSN 2448-6736.

In this work, the response of Ground Penetrating Radar (GPR) to geological characteristics of fluvio-acustrie soils is analyzed. GPR method is a very useful tool for structural studies of the geological media because it provides continuous profiles from the subsoil (radargrams). The identification of thin geological structures in the radar profiles allowed the evaluation of the detection capacity of the GPR Zond 12c for stratigraphical purposes. Its detection capacity depends on the achieved depth of penetration and resolution, on the transmitted wave frequency, and of the system used for acquisition and processing of the signals. The prospecting principle is based on the emission and reception of short electromagnetic pulses that are reflected by electric discontinuities related to physical or structural properties of the ground.
