Modelling for 3D migration of GPR data

John C. Bancroft

ABSTRACT

The acquisition of 3D ground penetrating radar (GPR) is accomplished by shooting a number of 2D lines across the target area. Typical processing of this data includes 2D migration of each line followed by interpolation to a 3D grid. This process produces high resolution of the subsurface along the 2D lines, but poor resolution between these lines. My intent is to model the acquisition process to identify features that may improve the 3D resolution.
