    • Abstract
  • Use called finite-difference time domain method(FDTD) a forward modeling for drift ground penetrating radar(GPR) is established by explicit second-order finite difference approximation.Using ideal stability conditions and super absorbing boundary conditions,some typical models in drift are simulated to investigate the characteristic of drift GPR pulled ahead profile.The shape and energy distribution of direct wave is mainly influenced by drift,while the energy distribution of reflected wave is influenced mainly by the interface between coal and rock.
