Abstract

A fast diffraction tomography algorithm for ground penetrating radar is derived in this paper. The algorithm uses the first born approximation and the dyadic Green´s function for a two layer medium to get a linear forward model that takes into account the planar air-soil interface. The forward model is then inverted using Fourier transform and this can be implemented with FFT, so the algorithm can reconstruct object rapidly. Numerical examples are provided to illustrate performance of this algorithm.
