用扫频成像法探测浅层管道

Exploring Shallow-Buried Pipeline with Scanning Imaging Technique

针对超宽带雷达探测浅层管道存在的困难,依据时频变换方法,提出了用扫频成像法探测深度在2.5m以内的埋地管道。采用矢量网络分析仪对不同间距的两条管道进行了伪彩色成像,经信号处理后得到了准确的三维立体图像。

Being aimed at the existent problems of exploring shallow-buried pipeline with hyper width radar,this article brings out the method of scanning imaging that depends on the way of the meta of time and frequency to explore the buried pipeline with 2. 5 m depth. By use of vector network analyzing instruments to make fake color images for the two pipelines with different intervals,the accurate three-dimensional pictures have been obtained after signal handling.
