摘要：

A fully three-dimensional, finite-difference time-domain (FDTD) model of a ground-penetrating radar is described, The FDTD simulation completely models the transmitting and receiving antennas, the antenna feeds, the dispersive earth, and the buried object, Results of scattering from three different buried cylindrical pipes are compared to previously measured results for a one-third size scale model of an actual radar and are shown to be in good agreement.
