A hybrid method is presented for modeling realistic ground penetrating radar systems to detect multiple underground conducting or dielectric targets. The model combines the method of momentpsilas solution of the frequency domain thin-wire electric field integral equation to treat the dipole antennas and the finite difference time domain technique to handle medium stratification and buried targets. The capabilities of the moment method solution of the thin-wire electric field integral equation and general finite difference time domain solution of Maxwellpsilas equations regarding the scattering of arbitrary shape objects in multilayered media are combined to efficiently simulate the electromagnetic behavior of the system. Some problems of practical interest are simulated using the proposed method and the capabilities of this technique to detect multiple buried arbitrary shape targets are discussed.
