A combined method of the non-uniform fast fourier transform (NUFFT) migration and the least-square based matching pursuit decomposition (MPD) algorithms is proposed to obtain better discrimination and interpretation for subsurface from ground penetrating radar (GPR) signals. By using the modifled NUFFT migration algorithm, a fast and high resolution GPR reconstruction can be obtained with an additional reduction in storage and computation requirements. By incorporating the MPD algorithm into a migration method, denoised reconstructions are obtained to enhance objects detection, including the identiflcation of objects' geometries and the estimation of their sizes and locations. Several examples from synthetic data and fleld data are demonstrated to establish the efiectiveness of the synergic efiect by comparing it with the conventional migration methods.
