T1 Location of Steel Reinforcement and Other Reinforcing Elements using 3D GPR JF Transactions on Transport Sciences YR 2009 VO 2 IS 4 SP 150 OP 157 DO 10.5507/tots.2009.022 UL https://tots.upol.cz/artkey/tot-200904-0002.php 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.
