    • FDTD simulations of multiple GPR systems 

      Oǧuz, Uğur; Gürel, Levent (IEEE, 2003-06)
      A multiple-GPR detection system was simulated. The main advantage of such a system was that it saves time by detecting both the transverse and the longitudinal positions of the target by a B-scan measurement, whereas the ...

    • Frequency responses of ground-penetrating radars operating over highly lossy grounds 

      Oğuz, U.; Gürel, Levent (IEEE, 2002)
      The finite-difference time-domain (FDTD) method is used to investigate the effects of highly lossy grounds and the frequency-band selection on ground-penetrating-radar (GPR) signals. The ground is modeled as a heterogeneous ...

    • Three-dimensional FDTD modeling of a GPR 

      Oğuz, Uğur; Gürel, Levent (IEEE, 2000)
      The power and flexibility of the Finite-Difference Time-Domain (FDTD) method are combined with the accuracy of the perfectly-matched layer (PML) absorbing boundary conditions to simulate realistic ground-penetrating radar ...

    • Three-dimensional FDTD modeling of a ground-penetrating radar 

      Gürel, Levent; Oğuz, U. (IEEE, 2000)
      The finite-difference time-domain (FDTD) method is used to simulate three-dimensional (3-D) geometries of realistic ground-penetrating radar (GPR) scenarios. The radar unit is modeled with two transmitters and a receiver ...

    • Transmitter-receiver-transmitter configurations of ground-penetrating radar 

      Gürel, Levent; Oğuz, U. (Wiley-Blackwell Publishing, Inc., 2002)
      Three-dimensional ground-penetrating radar (GPR) geometries are simulated using the finite difference time domain (FDTD) method. The GPR is modeled with a receiver and two transmitters with arbitrary polarizations in order ...

    • Transmitter-receiver-transmitter-configured ground-penetrating radars over randomly heterogeneous ground models 

      Gürel, Levent; Oğuz, U. (Wiley-Blackwell Publishing, Inc., 2002)
      Ground-penetrating radar (GPR) problems are simulated using the finite-difference time-domain (FDTD) method. The GPR model is configured with arbitrarily polarized three antennas, two of which are transmitting antennas fed ...
