| Abstract: | Based on Huygens' Principle, a 3D diffraction stack method is specified to correct the Ground Penetrating Radar (GPR) data's migration and image. In the experiment, to get transmitting narrow band pulse required by high resolution GPR, we use Sweep Frequency Technique (SFT) to generate source wide band signal and to collect reflected signal. At last through processing the experimental data, 3D higher resolution image of underground objects is obtained. |
