Title: FDTD investigation on GPR detecting of underground subsurface layers and buried objects
Abstract: To get a better understanding of the Ground penetrating radar (GPR) response, a two dimensional (2-D) finite difference time-domain (FDTD) computational model for underground detection of subsurface layers (concrete and clay) and buried objects (metal bar/strip, water/oil pipe, crack) is presented. For the model, the electromagnetic differential Gaussian pulse is used as the GPR source, the uniaxial perfectly matched layer (UPML) medium is adopted for truncation of the FDTD lattices. The FDTD simulation result of GPR B-scan response is obtain, and the influence of some parameters including buried depth, conductivity and geometry of the object on the characteristic of the back wave the object scattered is discussed.
