As you may have heard, GPR equipment is used to map structures and detect objects buried underneath construction sites. It detects man-made objects by sending radio waves to the sub surface that reflect back signals that develop a map of the construction site.
The radio waves have a 1 to 10000 MHz frequency range to map structures underneath the ground, including metallic and non-metallic structures.
GPR equipment has been in use as early as the 1970s. The GPR systems can:
-Locate buried utilities
-Assist in forensic investigations
-Assist in mine site evaluation
-Be used for archaeological digs
-And even be used to measure the thickness and quality of snow and ice at ski slopes.
GPR has a simple functionality. It sends weak radio frequency underneath the ground to reflect back echoes that come from detected man made objects. With that information a computerized image is developed to map structures underneath the ground. Based on the time delay and strength, the GPR equipment can identify the depth of obstructive objects.
How deep can GPR equipment detect material underneath the ground?
It all depends on the frequency level of the antenna how far the GPR penetration can go to detect metallic and non-metallic objects.
GPR equipment can conduct GPR penetration for the following sub surfaces:
-Ice
-Rock
-Soil
-Asphalt
-Concrete
-Fresh Water
-Wood
-Clay
-Silt
The lower the frequency the deeper the GPR systems can penetrate a surface. However, as the frequency lowers, resolution drops.
How far GPR systems can see all depends on the physical limits the surface area puts up for GPR penetration. For example, any energy absorbing material will make it very hard for GPR equipment to detect their locations. GPR scanning is a very sensitive measuring system yet very accurate system.
