Principle of Georadar and simulation of its operation by the Reflexw software

This paper is devoted to the study by simulating the propagation of electromagnetic waves of ground radar (GPR) in geological environments (heterogeneous). The latter is used as a method of geophysical prospecting based on the analysis of the spread of the diffraction and reflection of electromagnetic waves in high frequency (0.1 MHz to 2.6 GHz). A number of models have been designed to simulate the varieties of geological conditions. We used the method of finite differences in the time domain FDTD method [1], which is based on the code of scientific computing software Reflexw simulation [2]. During the spread of radar signal in a geological environment, we note that the signal decreases because of the phenomenon of absorption and reflection, and we find that the physical setting that has a great influence on the conduct of the wave in different geological environments is the effective permittivity.
