Ground penetrating radar (GPR) is a shallow geophysical survey technique used to identify underground bodies and structures by digitally identifying changes in electromagnetic signals. The technique is based on the propagation, reflection, and scattering of high-frequency (10 MHz to 2 GHz) electromagnetic (EM) waves in the subsurface. For the study normal fault in Büyük Menderes Graben, western Turkey. GPR is capable of resolving faults by imaging offset stratigraphic reflectors or reflection from the fault plane. In this paper there use 250 MHz and 500 MHz antennas for receiving the GPR data.
