Ground penetrating radar systems: pick the frequency for the job.
Ground-coupled radars from 100 MHz for depth to 1.6 GHz for the finest detail, and the acquisition and processing software to go with them.
SHRS series
Higher frequency, finer detail; lower frequency, deeper reach. One software suite across the range.
SHRS-R900
900 MHzDepth 0.8–1.5 m in favourable ground
Tunnel linings (lining thickness, voids, debonding, rebar and steel arches), reinforced concrete (rebar layout, voids, cracks) and pavements (layer thickness, voids, settlement, moisture).
Hand-held or towed · rugged tablet
SHRS-R400
400 MHzDepth 2–4 m in favourable ground
Engineering geology, road and bridge defects, municipal utilities, tunnel quality control and retaining walls.
Hand-held or on a survey cart · rugged tablet
SHRS-R200
200 MHzDepth 5–8 m in favourable ground
The R400 fields, deeper: shallow geological hazards, utility detection and leak detection.
Hand-held or on a survey cart · laptop
SHRS-R100
100 MHzDepth 10–15 m in favourable ground
Geological hazard assessment, engineering geology, ahead-of-face prediction in tunnels and landslide investigation.
Hand-held · laptop
Also in the range: a 1.6 GHz antenna for the finest detail, up to 0.8 m in favourable ground — concrete, rebar layout and poorly compacted zones in bridge decks.
| Model | Frequency | Depth in favourable ground | Typical use |
|---|---|---|---|
| 1.6 GHz antenna | 1.6 GHz | up to 0.8 m | Concrete, rebar layout, poorly compacted zones in bridge decks |
| SHRS-R900 | 900 MHz | 0.8–1.5 m | Rebar, tunnel lining, pavement layers |
| SHRS-R400 | 400 MHz | 2–4 m | Concrete, voids, retaining walls, utilities |
| SHRS-R200 | 200 MHz | 5–8 m | Roads, bridges, municipal pipelines |
| SHRS-R100 | 100 MHz | 10–15 m | Geology, deep exploration |

A stepped-frequency array radar
Eight transmit and receive channels in one clock domain, across a wide band, make a radar array that maps a full swath in one pass and delivers a 3D volume instead of single profiles. The radar core will be our own direct-sampling SDR board, and the processing RsGprProc. It is aimed at utility mapping and large-area surveys, where survey time is the cost.
Design stage. It will be used on our own surveys first.
Frequently asked
How deep can you see?
From up to 0.8 m at 1.6 GHz and 0.8–1.5 m at 900 MHz to 10–15 m at 100 MHz, in favourable ground. Clay and saline soils attenuate the signal; we advise on the frequency for your ground before you buy.
Which frequency should I start with?
For utilities and general site work, 400 MHz. Add 900 MHz, or 1.6 GHz for the finest detail, if concrete and pavement are a large part of your work, 200 MHz if your targets lie below four metres.
Can I see results before buying?
Yes. We can process a dataset acquired with the model you are considering, and arrange a demonstration in Belgium.
