3 Cobra WiFi GPR a new Ground Penetrating Radar researchers identify objects below ground. It works in a multifrequency band from 100 to 900 MHz and replaces 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 Depends mainly on antenna frequency, water content and soil conductivity. Typical penetration with Cobra Maximum 30 feet of penetration in dry soil WiFi GPR is 5-15 feet. Rugged PC PC Antennas Transmitted wave R Buried object Antenna footprint 3-D Radar Depth Slice, horizontal view 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. Wall remains after excavation 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 Picture of buried wall remains after excavation.

4 Cobra WiFi GPR applications Just 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. Infrastructure & utility mapping Inspect internal structures and identify voids under; roads, airports, bridges, tunnels, railways, dams and buildings. Locate plastic, concrete, clay- or metal pipes. Map concrete before drilling, cutting or coring. Detect obstacles in front of directional drilling operations Environmental Locate hazardous waste, UST-location. Delineation of contaminant plumes and product spills. Map shallow lakes and rivers. Geology and mining Locate gemstone pockets in pegmatite. Find kimberlite, lateric nickel. Map internal structures and voids in soil. Locate cracks in bedrock and building stones. Snow and ice Airborne 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, foundations, burials and chambers. One of Radarteam Sweden AB most famous projects was when we discovered a year old woolly mammoth, well preserved in the permafrost ground of Siberia. The project is frequently show cased by Discovery Channel, Raising the Mammoth. Military and security Locate 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 forestry Locate agricultural and golf-green drainage tiles. Determine soil water content and conductivity. Map tree roots and rot in wood.
