介绍了探地雷达桩底岩溶探测原理及方法,研究了探地雷达图像数据的Ormsby带通滤波和频域背景去除的处理方法,实践表明该方法能有效提高探地雷达图像数据的解译水平。
The principle and method of ground penetrating karst detection in ground penetrating radar are introduced. The processing methods of Ormsby band-pass filtering and frequency-domain background removal of ground penetrating radar image data are also studied. The practice shows that this method can effectively improve the level of ground penetrating radar image data interpretation .
