ABSTRAK :
Ground Penetrating Radar (GPR) is a radar that uses electromagnetic waves sothat penetrate the ground, used for high resolution imaging. GPR function is detecting the existing material in the shallow subsurface. In this study author describe the process of propagation of GPR electromagnetic waves transmitted into the ground in simulation using the r2010b Matlab software by Finite-Difference Time-Domain (FDTD) metod. Visualization of the interaction of electromagnetic waves provides a sense of the relationship between the properties of the subsurface and GPR data. This can be created with a model from an existing area or a point below the subsurface. Synthetic data obtained can be used to promote understanding of the author as information about the space variability of subsurface properties. The purpose of this study is to find out what’s going on with the electromagnetic waves after transmitted from the GPR into the ground with influence of the dielectric permittivity of a material. GPR simulation steps by the FDTD metod determines the maximum time, pad grids for perfectly matched layer (PML), then start the simulation, next the result obtained from the simulation. From the survey result revealed that the electromagnetic waves transmitted by the GPR into the ground causing a reflection and refraction. This is caused due to the difference on material dielectric permittivity that dielectric permittivity of the free air is smaller than the air when it was in the soil and the object material. Keywords: Ground penetrating radar, electromagnetic waves, Finite-difference time-domain (FDTD), PML.
