探地雷达地下管线探测的三维成像

Three-Dimensional Imaging of Underground Pipelines Detected by Ground-Penetrating Radar

探地雷达凭借快速、高分辨率等优点,在地下管线探测中发挥了显著作用。文章简要介绍了探地雷达探测技术,结合工程实例,为了提供雷达信号的信噪比和分辨率,对采集的数据进行了速度提取、偏移归位等一系列的预处理。最后利用matlab开发平台,对其进行三维成像,图像直观可视,可精准定位管线。

Ground-penetrating radar with fast, high-resolution, etc., in the underground pipeline detection has played a significant role. This paper briefly describes the ground-penetrating radar technology. In order to improve the radar signal to noise ratio and resolution, with the engineering example, the collected data extraction speed, offset homing and a series of pretreatment were made. Finally, the three-dimensional imaging was realized by use of matlab development platform, the image is intuitive and visual, and it can locate the pipeline accurately.
