Ground Penetrating Radar Equipment For Sale
Ground Penetrating Radar (or GPR for short) is the general term applied to techniques which employ radio waves, typically in the 25 to 6000 MHz frequency range, to map structure and features buried in the ground (or indeed in man-made structures). More recently GPR has been used in non-destructive testing of non-metallic structures. The applications of GPR are many and varied, they include:
The applications of GPR are many and varied, they include:
- Fracture Mapping
- Voids Beneath Concrete
- Geological Stratigraphy
- Pipe and Barrel Location
- Utility Detection
- Water Table Mapping
- Road Bed Mapping
Geomatrix Earth Science is the European and US sales agents for Utsi Electronics, and we hold their Groundvue 3 250, 400 and 1000 MHz shielded antenna systems for hire. For Environmental investigations the Groundvue 2 with 50MHz is available. For geological investigations we supply the Groundvue 6C with 30MHz inline antenna.

Example Data Sets
NSGG Test Site UXO Master GPR Dataset
Displayed below is a C-scan (depth slice) taken from the master GPR dataset for Area 5 at the NSGG test site, Leicester. Data was collect using a Mala X3M with 500MHz antenna. A grid of traverses orientated NE-SW & SE-NW were acquired at a regular 1m interval. The data was processed, converted to depth and stacked to form a data cube. The depth slice illustrates all of the anomalies detected at 0.25m beneath the ground surface and shows many of the buried targets.
Metallic targets reflect all of the transmitted EM wave energy back to the ground surface and therefore the receiver. This makes GPR a good technique for UXO detection. However voids and structural material (masonry) can produce very similar targets depending on the site conditions and therefore it can be difficult to distinguish between cultural noise and UXO targets.
By integrating the results from the GPR data along with the EM61MK2 and Magnetic data it is possible to collate comprehensive information about the material properties of each anomaly and as a result distinguish between those which are likely to UXO and those which are not.

BBC Video Interview
Watch how the ground radar used in Madeleine McCann search works
Police investigating the disappearance of Madeleine McCann have begun using ground-penetrating radar equipment on scrubland in the Algarve.
The equipment is being used to look for signs of disturbed earth and Chris Leech from Geomatrix explains how the device works on the BBC.
