Sažetak
The paper deals with the work of georadar and its applications. Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, voids and cracks. To be able to achieve this feat, gprMax program, which is open source software that simulates electromagnetic wave propagation, is used. It uses Yee's algorithm to solve Maxwell’s equations in 3D using the Finite-Difference Time-Domain (FDTD) method. The simulations presented in this paper serve as an opener to the subject in further development of various models for EM propagation with hertzian dipole as a source.
