Migration of Ground Penetrating Radar With Antenna Radiation Pattern Correction
IEEE Geoscience and Remote Sensing Letters, 2022Migration can reconstruct the geometric structure of a subsurface object from the ground penetrating radar (GPR) data. However, a GPR antenna is usually simplified as an ideal point/line source of normal migration algorithms, which ignore the influence ...
