Simulasi Perambatan Gelombang Georadar (GPR) pada Suatu Media Berlapis
Abstract: The simulation of
the wave propagation of the radar in the sub-surface was very important to be
understood before being carried out of field acquisition, to maximize the
design of the acquisition and to optimized radar gram data’s. One of the
approaches in the simulation of the data was to use propagation modeling of the
electromagnetic wave by using the Finite Difference Time Domain solution
(FDTD). Modeling of electromagnetic wave propagation in the GPR requires a
solution of Maxwell’s equations or present a finite-difference time-domain
(FDTD) solution of Maxwell’s that permit accurate computation of the radiated
field from a transmitting antenna. Propagating through the air-earth interface,
scattering by subsurface targets and reception of the scattered fields by
receiving antenna. This technique is second-order accurate in time and fourth-order
accurate in space. In this paper, I demonstrate the synthetic radar gram by
applying this technique to two-dimensional examples from a subsurfaceof
stratified media.
