How does GPR work?

Ground Penetrating Radar sends a radar pulse into the ground. This pulse reflects or responds as it encounters contrasting soil layers or objects with different dielectric properties. The electrical contrast between materials determines the reflection coefficient, which affects how much signal could possibly reflect back to the instrument. Hence, materials with a high reflection coefficient are able to produce a stronger response. For instance, metal in concrete produces a greater signal than clay pottery in soil because there is a greater difference in reflection coefficients and electrical contrast for metal in concrete than for clay in soil. Note that under some situations strong reflections from shallow metal may make it tough or impossible to see deeper metal objects. This is because all or most of the radar pulse reflects or scatters off the shallow object before reaching a deeper target.

The displayed depth of a target, object, or soil/rock layer is a function of time. In other words, the instrument only measures the time the GPR pulse travels from the instrument’s transmitter, reflects off an object or layer with different dielectric properties, and returns to the instrument’s receiver. Therefore, displayed depths are estimates and are only as accurate as the chosen average velocity. Average velocities can change across a survey area, affecting the depth estimate’s accuracy. Some basic examples of suggested velocities for different soils and materials are shown in the chart below :
Suggested Velocity Chart

If in doubt, a value of 0.0328 ft/ns or 0.10 m/ns is often selected for non-conductive materials and can be changed during post processing. Some of the GPR systems allow hyperbola matching of anomalies to determine the proper velocity. Hyperbola matching frequently works best when crossing perpendicular to path of a smaller diameter cable or pipe. Hyperbola matching can lead to a poor velocity estimate when a cable or pipe is crossed at an angle or if the cable or pipe has a large diameter. Above all, GPR units accurately measure the travel time of a radar signal regardless of the average velocity value.

GPR Limitations

First and foremost, ground penetrating radar works best with materials that have low electrical conductivity. For example, air, rock, ice, sand, gravel, plastic, and concrete. In effect, GPR does not do well transmitting a signal through electrically conductive materials such as water (note distilled water and ice are generally an exception), clay, and metal. Depending on the desired depth of investigation, poor conditions are not always a problem for shallow GPR surveys. Therefore, it is important when doing surveys on land to research the soil type and its inherent properties. For more information, reference the map below to view areas where GPR will work best.

Ground Penetrating Radar Suitability Map
GPR Soil Suitability Map

GPR systems come in a number of different antenna frequencies that work better for certain applications. As a general rule, higher frequency antennas offer more detail or better resolution. On the other hand, higher frequencies cannot penetrate as deep into the ground because the signal scatters quickly and is more easily absorbed. As a rule, lower frequency antennas will penetrate deeper into the subsurface but respond poorly to smaller objects or targets of interest because of the large wavelength. Therefore, the results will not be as detailed. Nonetheless, in both cases more stacks per record will commonly lead to greater depths and more detail in difficult conditions. Unlike conventional GPR systems that typically stack 10’s of records per trace, Sensors & Softwares’ Ultra receiver is capable to stacking over 65,000 records per trace. Contact GPR Rental to discuss antenna frequencies for your site investigation.

Depending on target size and depth of investigation, the following are common recommendations for antenna frequency use:

1000Mhz antennas uses include concrete scanning and infrastructure assessment. This includes locating wire mesh, conduit, high tension cables, rebar, slab thickness, and conditions immediately beneath the slab. Approximate depth of penetration in perfect conditions: less than 36 inches

500-200Mhz antennas uses commonly include locating utilities, voids, graves, foundations, drain tiles, underground storage tanks, archeological targets, and characterizing shallow geology. Approximate depth of penetration in perfect conditions: less than 6ft for 500MHz, less than 12ft for 250MHz, and less than 15ft for 200MHz (note pulseEKKO or Noggin Ultra receivers offer greater depths of penetration)

100-12.5Mhz antennas uses often include geologic mapping and geotechnical applications such fault/sinkholes locating, bedrock depth verification, soil stratigraphy mapping, water table delineation, and bathymetry. Approximate depth of penetration in perfect conditions: less than 30ft for 100MHz and less than 65ft for 50MHz (note pulseEKKO or Noggin Ultra systems offer greater depths of penetration)

pulseEKKO or Noggin with Ultra receiver antennas frequently obtain depths twice as deep as a conventional system. For example, a Noggin 100 Ultra may reach depths of +/- 50ft in soil conditions where a Noggin 100 is limited to a depth of 25ft.

The antennas and digital video logger mounts in a variety of configurations to handle differing site conditions and environments. The most common being the SmartCart, SmartTow, and SmartHandle (not all options may be available.)

The Noggin series is more customizable than the LMX200 in that the users can set more parameters for their survey. In other words, the LMX200 is a simplified Noggin with a dedicated 250MHz antenna intended as a “Start-up and run” system. In contrast, many of the user controls for the Noggin’s system settings are adjustable to customize and fit specific parameters and survey conditions. Also, the user has the option to order multiple antennas for one or more configurations (e.g., SmartCart, SmartHandle, or SmartTow). Unlike the pulseEKKO design, these systems can only use one antenna at a time.
