Abstract
Local Plane-Wave processing is used to image synthetic Ground Penetrating Radar (GPR) data in a non-homogeneous background. 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 propagate the data over a local image. The local images are compared with images obtained from diffraction stack processing. The effect of the irregular wavenumber sampling on the point spread function is illustrated. The local image using all corrections shows a great reduction in image distortion compared to diffraction stack processing.
