SIMULTANEOUS LOCATION OF BOTH SHALLOW AND DEEP PIPES

The new Cobra GPR collects data from hundred thousands of pulse reflections each second to helpresearchers identify objects below ground. It works in a multifrequency band from 100 to 900 MHz andreplaces 2-3 antennas with different frequencies used by other and older GPR systems.

How it works

An antenna sends pulses of radar energy into the ground and

another receives the information that bounces back up.

Depth Penetration

3-D Radar Depth Slice, horizontal view

A 3-D software translate several 2-D radar profiles into a 3-D

map, depth slice, at different depths. For full 3-D, the spacing

between 2-D survey lines must be very close (��4).

The depth slice below shows a buried Roman building wall

remains, at Carnuntum, Austria.

Buried remains of a building at 2 m depth shown as a 20 cm

depth slice. Survey map: 40 square meters, based on 40 m

long GPR-profiles separated by 50 cm.

Depends mainly on antenna frequency, water content and soil

conductivity. Typical penetration with Cobra WiFi GPR is 5-15 feet.

Maximum 30 feet of penetration in dry soil w.

Cobra WiFi GPR – a new Ground Penetrating Radar

Infrastructure &utility mappingInspect internal structures and identify voids under; roads, airports, bridges, tunnels, railways, dams and buildings.Locate plastic, concrete, clay- or metal pipes. Map concrete before drill-ing, cutting or coring. Detect obstacles in front of directional drilling operations

EnvironmentalLocate hazardous waste, UST-location. Delineation ofcontaminant plumes and product spills. Map shallow lakes and rivers.

Geology and miningLocate gemstone pockets in pegmatite. Find kimberlite, lateric nickel. Map internal structures and voids in soil. Locate cracks in bedrock and building stones.

Snow and iceAirborne mapping of snow- and ice thickness. Find crevasses and avalanche victims. Profile ice roads in detail. Glaciology research.

Archaeology & forensics

Pre-excavation mapping of buried structures, founda-

tions, burials and chambers.One of Radarteam Sweden AB most

famous projects was when we dis-covered a 20.000 year old woolly mam-

moth, well preserved in the permafrost ground of Siberia. The project is frequently

show cased by Discovery Channel, “Raising the Mammoth”.

Military and securityLocate tunnels, bunkers, hidden weapons and drugs. Find land mines and unexploded ordnance (UXO). Through wall imaging. Rescue operations: Locate trapped victims under collapsed buildings, landslides.

Agricultural and forestryLocate agricultural and golf-green drainage tiles.Determine soil water content and conductivity.Map tree roots and rot in wood.

Cobra WiFi GPR applicationsJust like X-ray and ultrasound can image the internal of your body, the Cobra WiFi GPR can be used to image the internal of different materials and structures.
