OPTIONAL REAL TIME SAMPLING
THE SMART GPR
The COBRA CBD WIRELESS GPR collects data from hundred thousands of pulse reflections each second to help researchers identify objects below ground.
It works in a
multi frequency band from 50 to 1400 MHz, thus replacing several antennas with different frequencies used by other and older GPR systems.
HOW IT WORKS
The unique CBD antenna transmits pulses with triple frequencies in a blended pulse form. The CBD antenna selects the optimal frequency needed for all layers and targets at different depths.
The CBD antenna data received can then be used for accurate velocity/RDP values for layers and targets via frequency analysis (using a proprietary formula - with
linear relation between reflected frequency and velocity).
3-D RADAR DEPTH SLICE, HORIZONTAL VIEW
A 3-D software translates 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 ( λ/4).
The depth slice below shows a buried Roman building wall remains, at Carnuntum, Austria.
Benefits:
GPR/Antenna system with rugged PC and cart
Multiple applications - 0-10 m depth range
Real-time working with 2x depth range and channel options
No additional survey needed
Best penetration and data quality in head-to-head tests
APPLICATIONS & USES (KULLANIM ALANLARI)
Geology and Mining
Locate gemstones pockets or find kimberlite, lateritic nickel, as well as cracks in bedrock and building stones. Map internal structures and voids in
soil .
Infrastructure & Utility Mapping
Inspect internal structures and identify voids, such as roads, bridges, tunnels, railways
and drains, and locate different types of material such as plastic, concrete, clay and metal pipes. Map concrete before drilling, cutting or coring. Detect obstacles in front of directional drilling operations.
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 and landslides.
Environmental
Locate hazardous waste, UST-location. Delineation of contaminant plumes and product spills. Map shallow lakes and rivers.
Snow & Ice
Complete airborne mapping of snow and ice thickness, which allows for the findings of buried items. Find crevasses and avalanche victims.
Profile ice roads in detail. Glaciology research.
Agricultural and Forestry
Locate agricultural and golf-green drainage tiles. Determine soil water content and conductivity. Map tree roots and rot in wood.
Archaeology & Forensics
Pre-excavation mapping of buried structures, foundations, burials
and chambers.
WHY
MULTI FREQUENCY ANTENNAS?
The COBRA CBD Frequency Advantage
COBRA CBD GPR uses a patent pending unique triple frequency antenna design (200, 400 and 800 MHz nominal frequencies). Because the CBD-antennas emits three ultra
wide band pulses (150% of nominal frequencies compared to 100% for conventional antennas), that overlap and
blend together it can replace multiple antennas with nominal frequencies between 200 and 800 MHz. (See frequency spectrum below)
• Mixed/blended data with
automatic optimum frequency selected through all depths in one single file.
•
Near surface data with high resolution/frequency and deep targets with lower required frequencies.
• No need to set frequency filters. The smart CBD antenna filters by itself.
• No ”dead zones” or blind spots in data due to blended frequencies.
• Calculate velocity directly from frequency content with
proprietary formula.
•
Real Time Sampling technology option
•
Air coupled operation without ringing. (Other antennas must be ground coupled to avoid ringing)
