Ground Penetrating Radar Systems
Precision Below the Surface
For over 30 years, US Radar has designed and built reliable ground penetrating radar systems that give clear results on the spot, even in the toughest conditions. Whether you are identifying underground utilities, confirming subsurface features, or conducting geophysical methods, our GPR technology is tested in the field and trusted by professionals all over the world.
We make it possible to see beneath the surface, without disturbing the ground. Built for accuracy, flexibility, and clarity, our GPR technology supports a range of applications from urban utility locating to remote ground surveys and archaeological digs.
What Is a Ground Penetrating Radar System?
A ground penetrating radar system uses low-power electromagnetic energy to detect and map subsurface materials. It sends short bursts of radar pulses into the ground using a transmitter antenna. When those radar waves hit something with different dielectric properties, such as a pipe, void, or rebar, they bounce back. A receiver antenna captures the return signal, producing a profile of the subsurface structures below.
This non-invasive GPR method is based on the interaction between electromagnetic properties and material composition, making it ideal for detecting everything from buried objects and utility lines to changes in soil conditions.
How GPR Systems Detect Subsurface Features
When radar waves hit a boundary, such as between soil and a pipe, they reflect back. The time it takes for the reflected signal to return tells us the object’s depth. The signal’s strength adds clues about the material’s size or makeup.
Several factors affect what we see:
• Electrical conductivity: Conductive soils absorb signals faster.
• Dielectric permittivity (or relative permittivity): Different materials change wave speed.
• Signal attenuation: As radio waves travel, they weaken.
Our depth calculations adjust for these factors. That gives us reliable depth readings. The result: accurate, field‐ready insight into what lies below.
Applications Across Industries
US Radar’s GPR technology helps solve real‑world challenges:
Utility locating – Scan for ground penetrating radar signals to find gas pipes, water mains, conduits, fiber cables, and more. You’ll reduce risk and avoid costly mistakes.
Construction projects – Spot subsurface anomalies ahead of digging. Locate rebar, post‑tension cables, or unexpected voids.
Concrete scanning – Pinpoint structural elements safely. Our GPR unit guides safe drills and saw cuts.
Geophysical methods – Map underground features like soil layers or ice thickness. Useful in environmental studies or remote surveys.
Archaeology – Unearth buried objects without upending sites. Preserve context by mapping before excavation.
That versatility makes GPR investigation vital for engineers, surveyors, researchers, and anyone working below the surface.
Choosing the Right GPR Technology
Every job needs the right tool. We’ve designed systems that fit your task:
• Higher frequency antenna offers sharper detail but only reaches shallow depths. Ideal for concrete scanning or tight urban zones.
• Lower frequency antenna covers more depth but with less resolution. Choose it for deep utility locating or geological surveys.
• Multi-frequency systems give you both depth and detail. Switch settings to suit soil changes or discovery levels in one scan.
• Common offset configuration and antenna pair setups offer flexibility in data layout.
• For post holes or foundation inspections, we offer single-borehole radar.
Pick the right setup, whether mapping one site or surveying mile after mile.
Data Interpretation and Processing
Collected GPR data becomes useful through smart tools. Our software helps with:
• Adjusting gain and contrast to bring out hidden layers.
• Overlaying radar data on satellite imagery or site plans.
• Annotating findings and exporting to widely used formats like .kmz, .dxf, and .shp.
You’ll identify subsurface objects, estimate material composition, and confirm the presence of known objects, using reliable data you can trust, share, and archive.

FAQs About GPR Systems
What is a ground penetrating radar system used for?
It detects and maps subsurface structures, like utility lines, buried items, and structural elements. Common uses include construction, geophysics, archaeology, and environmental surveys.
How deep can GPR systems detect?
Depth depends on frequency range and ground makeup. Low‑frequency antennas go deeper, and high‑frequency antennas show more detail. US Radar systems reach up to 100 ft with the 100 Series.
What affects GPR signal quality?
Electrical conductivity, dielectric permittivity, and signal attenuation determine signal clarity. Materials like wet clay or metal reduce visibility.
Can GPR detect all underground utilities?
Is GPR safe near people and structures?
Yes. GPR uses low‑power electromagnetic pulses and does not disturb the ground. It’s safe in sensitive areas and around infrastructure.
