AB This paper evaluates the results of the first experimental 3D GPR measurements by the DIBEKON scanner on a physical model. The objective of the series of measurements carried out was to determine the applicability of various types of antennae (800 MHz and 1600 MHz) in the detection of steel reinforcement and the influence of the measurement density on the quality of the resulting image of the environment examined.
