| Abstract | Stolt migration is one of the useful GPR imaging algorithms, which has the advantage of fast implementation speed. The fast Fourier transform of integral formula in image reconstruction is realized by coordinate transformation and done through interpolation. Interpolation determines the effectiveness of imaging directly. In the practical applications, zero-fill interpolation in time-domain is used to improve accuracy, but which will increase the computational complexity. In this paper, non-uniform fast Fourier transform (NUFFT) algorithm is introduced to realize the fast computing of integral formula in image reconstruction directly. The simulation results show that this method achieve good results. |
