GPR dataset: pulsed radar and SFCW data for rebar detection (experimental data)

GPR data corresponding to the article "Rebar detection: Comparison of stepped frequency continuous wave and pulsed GPR" presented in the 7th International Conference on Smart Monitoring, Assessment and Rehabilitation of Civil Structures (SMAR 2024). This work presents a comparison in rebar mapping between two GPR systems with different modulation techniques: Stepped frequency continuous wave (SFCW) and pulsed radar. The SFCW system used has a frequency range of 400-6000 MHz, while the pulsed system used a ground-coupled central frequency antenna of 2.3 GHz. Measurements were conducted on laboratory specimens, with rebar diameters ranging from 8 to 32 mm. Three different specimens were used, with one for calibration and other two to analyze both the horizontal and vertical resolutions of the frequency antennas.
