Ground Penetrating Radar GPR

Ground Penetrating
Radar (GPR)

Ground Penetrating Radar (GPR) also called georadar, is an electronic equipment for testing geophysical properties of the soil and rocks. This device works on the principle of counting delays electromagnetic (EM) pulses of high frequency (10 - 1000 MHz) transmitted by the transmitting antenna, which is reflected from the various centers of the layers (lithological boundaries) are received by the receiving antenna and transmitted to a central processing unit for counting the time delays return wave. Across borders reflecting the radar signal must be understood boundaries between the centers of differing value of the dielectric constant (E). Various rocks and materials are characterized by different values of the dielectric constant.
