摘要
基于惠更斯原理三维探地雷达数据叠加偏移处理方法 ,对实验数据进行了三维成象处理。并用频域扫频方法产生宽频带信号 ,通过网络分析仪采集频域回波信号数据 ,获得高分辨率探地雷达所需要的窄脉冲信号。
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.
