Abstract

Local Plane-Wave processing is used to image synthetic GPR data. Numerically calculated Green's functions are used to back propagate the data down to a Green's function node, in the center of the region to be imaged. From the Green's function node a Plane-Wave approximation is used to back propagate the data over a local image. The data are correctly positioned in the wavenumber space and are re-sampled to a Cartesian grid. The data are then inverted using an IFFT.
