ESTIMATION OF GROUND-PENETRATING RADAR (GPR) SIGNAL PARAMETERS IN PHYSICAL MODELING OF SAND AND GRAVEL MIXTURE
The article considers the problems of using GPR in exploration of sand and gravel deposits. The results of physical modeling are given on an example of three models, which reflect different geological situations. First one sparse large boulders, second one densely packed small gravel and the last one inclusions of conductive carbonaceous rocks. The relative humidity and apparent resistivity parameters are also taken into account. Based on the simulation results, were received GPR images of the local inclusions used at different humidity. The parameters influencing the formation of the diffracted wave and its dynamic characteristics are also studied.
