Using GPR technique on historical limestone quarry from Magura Calanului – Hunedoara County

Abstract

The GPR technique has proven useful in a wide range of environmental, geological and engineering applications, with very encouraging prospects for results in other sciences, such as archaeology. Specialists in archeology, geology, and even those in the field of construction recognize this method as a precise and fast one. The principle is simple: emitted radio waves travel at a speed that depends on the material in which they propagate. The high-frequency radio waves used by the GPR system are sensitive to both changes in conductivity and dielectric properties of the materials traversed. The electromagnetic characteristics of materials are related to their composition and their degree of saturation (Zielińskey et.al, 2016). This affects the propagation speed of radio waves and the attenuation of electromagnetic waves in the medium under study (Reynolds 1997).
