Ground Penetrating Radar (GPR) uses radar waves to detect objects and surfaces buried underground or inside any other medium. The device emits a harmless radar wave at a particular frequency which reflects or is absorbed by differing buried objects or layers. Waves reflected by these buried items are then bounced back to a receiver and displayed in real time on the field computer. This technique is non-destructive, non-invasive, and highly adaptable for many situations.
NLURA uses a GSSI 3000 field unit equipped with three potential antenna choices:
- 200 mHZ
- 400 mHZ
- 900 mHZ
Antenna choice is dependent on the desired depth of a particular target or surface; each antenna has the ability to achieve a certain depth of penetration under ideal circumstances.
NLURA uses this equipment for various applications including:
- Archaeological Site Analysis
- Deterioration Analysis
- Utility Locating
- Bathymetry
- Geologic Investigations
- Sediment lithology
- Bedrock determination
- Permafrost detection
