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.

本数据集对应发表于第7届土木结构智能监测、评估与修复国际会议（SMAR 2024）的论文《钢筋检测：步进频率连续波与脉冲探地雷达对比研究》中的探地雷达（Ground Penetrating Radar，GPR）数据。

本研究对比了两种采用不同调制技术的探地雷达系统在钢筋成像中的性能表现：步进频率连续波（Stepped Frequency Continuous Wave，SFCW）系统与脉冲雷达系统。所用SFCW系统的工作频段为400~6000 MHz，而脉冲雷达系统搭载了中心频率为2.3 GHz的地面耦合天线。测试实验在实验室试件上开展，所用钢筋直径范围为8~32 mm。本次实验共使用3组不同试件：1组用于校准，剩余2组分别用于分析该频段天线的水平分辨率与垂直分辨率。
