Ground Penetrating Radar Target Signal Echo Analysis and Engineering Application

针对探地雷达中探测介质识别困难的问题,以探地雷达在校园、居民小区以及核电站厂区三种不同环境中的探测实例为依据,通过波形对比分析详细介绍了各类不同波形的形成原理,以探测波形特点为依据实现了对道路质量的评估与地层未知介质的有效识别,并对照探测区域的施工图纸对探测结果进行了验证。探测结果与施工图纸相符,不同属性介质的探测波形在信号强度与波形特点上有明显的区别,以波形特点为基础可实现对地层介质快速识别,能够为建设工程提供可靠的地层资料。

Aiming at the difficulty of detecting medium in ground penetrating radar, based on the detection examples of ground penetrating radar in three different environments of campus, residential area and nuclear power plant area, the formation principle of various waveforms is introduced in detail through waveform comparison analysis. Based on the characteristics of the detected waveforms, the assessment of road quality and the effective identification of the unknown medium in the formation were realized, and the detection results were verified against the construction drawings of the detection area. The detection results are consistent with the construction drawings. The detection waveforms of different attribute media have obvious differences in signal strength and waveform characteristics. Based on the waveform characteristics, the formation medium can be quickly identified, and reliable formation data can be provided for the construction project.
