在加拿大东部复杂的河流/风沙环境中，记录了一组40通道大口径探地雷达(GPR)数据。这些数据是以通常与地震反射调查有关的多通道格式收集的，并被直接输入标准地震处理程序(滤波、静态校正、共中点采集、速度分析、正常和倾角时差校正、叠加和深度偏移)。结果表明，与单通道记录相比，在降噪和穿透深度(通过叠加)以及空间定位和减少衍射伪影(通过偏移)方面都有显著改进。这些特征增加了可靠解释构造和地层细节的可能性。因此，无需开发任何新的软件，探地雷达数据处理技术就达到了地震勘探中当前的能力、灵活性和可获得性的水平。
A 40-channel wide‐aperture ground penetrating radar (GPR) data set was recorded in a complicated fluvial/aeolian environment in eastern Canada. The data were collected in the multichannel format usually associated with seismic reflection surveys and were input directly into a standard seismic processing sequence (filtering, static corrections, common‐midpoint gathering, velocity analysis, normal‐ and dip‐moveout corrections, stacking and depth migration). The results show significant improvements, over single‐channel recordings, in noise reduction and depth of penetration (by stacking), and in spatial positioning and reduction of diffraction artifacts (by migration). These characteristics increase the potential for reliable interpretation of structural and stratigraphic details. Thus, without having to develop any new software, GPR data processing technology is brought to the same level of capability, flexibility, and accessibility that is current in seismic exploration.
