三维探地雷达在地下金属管线定位探测中的应用研究

Application of 3D Ground Penetrating Radar in location detection of underground metal pipelines

现今为止,基于探地雷达(GP R)的地下金属管线相关工作只是单纯限于判断金属管线的埋深,可对地下金属管线的非接触现场检测与定位判断尚缺乏方便、高效的方法。针对这一情况,提出三维探地雷达在地下金属管线定位探测中的应用研究。首先设计出信息采集板设计,便于各项数据的采集,之后对探地雷达信号进行预处理以实现管线的最终定位。

Up to now,the related work of underground metal pipeline based on ground penetrating radar(GPR)is only limited to determine the buried depth of metal pipeline.There is no convenient and efficient method for non-contact onsite detection and location judgment of underground metal pipeline.In view of this situation,the application of 3D Ground Penetrating Radar in the location detection of underground metal pipelines is proposed.Firstly,the design of information acquisition board is designed to facilitate the collection of various data,and then the GPR signal is preprocessed to realize the final positioning of the pipeline.
