| Outline of Final Research Achievements |
In this study, we have analyzed detection characteristics of a subsurface displacement by ground penetrating radar (GPR) using the finite-difference time-domain (FDTD) simulation with graphic processing units (GPUs) cluster. Inhomogeneous subsurface with many randomly placed scatters which are different in size and electric permittivity have been modeled, we have computed detection characteristics of subsurface displacement in the inhomogeneous subsurface models using the FDTD method. We have estimated the detection of subsurface displacement by cross correlation value between homogeneous and inhomogeneous GPR profiles. Moreover, we have shown that the use of GPU cluster is much more faster and practical than conventional method.
