Abstract :
A multilayered diffraction tomography algorithm for ground penetrating radar is derived in this paper. The algorithm considers the planar air-soil interface and uses the thought of the equivalent speed to solve the problem of multilayered medium. The first Born approximation and the dyadic Green´s function are adopted to construct a linear forward model that inverted by fast Fourier transform to meet the requirement of small calculation, so we can real-time reconstruct the buried objects. Simulation results are provided to illustrate performance of this algorithm.
