This paper focuses on 3-dimensional (3D) migration of non-gridded ground penetrating radar (GPR) data. We acquired a gridded dataset in a sandpit with 2.5 cm interval, which meets the Nyquist spatial sampling criterion for an antenna of 500MHz center frequency. We applied non-gridded 3D migration after re-sampling the data in two different ways, i.e. re-sample in x- and/or y- directions, random pick a part of sampling points. Based on the results, we discuss the artifacts that caused by aliasing while reconstruct the 3D GPR image. For simple targets, it is possible to reconstruct the image with larger interval than that defined by the Nyquist spatial sampling criterion. The result indicates that it is possible to reduce the data density. |
