    On the frequency-band selection for ground-penetrating radars operating over lossy and heterogeneous grounds
    (IEEE, 2001-07) Oǧuz, Uğur; Gürel, Levent
    The frequency-band selection for ground penetrating radars operating over lossy and heterogenous grounds was discussed. The simulations were carried out using perfectly matched layer (PML) absorbing boundary conditions (ABC). The results demonstrated that for conductivities below 0.5 S/m the change in centre frequency does not influence the energy scattered from the deeper target. The selection of the center frequency thus influences the GPR measurements for the measurements performed over a highly-conducting soil.
