How deep does GPR see?
Ground Penetrating Radar is a technology that is often used for identifying, locating, and mapping embedded objects, changes in material properties, and voids. This technology utilizes various frequencies of electromagnetic waves and therefore, requires a variety of antennas. As a rule of thumb, the higher the frequency of the antenna, the more restricted the depth of investigation but the higher the resolution in seeing small or closely-spaced objects. This does, however, depend on the material properties of the medium in question. For example when testing concrete, a 1500 MHz antenna will typically see down to 18 inches below the test surface. This investigation depth may be significantly shallower if the same antenna was used on clay-saturated soil.
