REAL TIME SAMPLING

The COBRA PLUG-IN GPR uses Real Time Sampling of the radar signal. Today major manufacturers use conventional interleaved sequential sampling, giving only a down converted replica of the real signal.
The Real Time Sampling allows for 32,000 stacks/second resulting in an amazing 45 dB increased signal-to-noise ratio.

WIRELESS

Wireless Bluetooth connection between GPR and control unit replaces interfering coax-cables and fragile fibre optic links.
An Ultra Rugged Mesa PDA with embedded software is used for
data collection.
Data is stored in standard SEGY geophysical format.
The complete GPR-unit plugs into a single SUBECHO Antenna, any selectable model. No need for bistatic configuration.

High Penetration

The high penetration antennas from Radarteam provides the highest possible penetration.

These antennas have been successfully used in:

Deep geological and geotechnical surveys
Embankment dam safety control, structure/voids
Mapping of fracture zones in bedrock with overburden
Sand and gravel deposit surveys
Mapping of water- and sediment depth in rivers
Mapping extension of mineralization areas
Geohydrological and glaciological survey

SUBECHO-40

The SUBECHO-40 is recognized worldwide as the best GPR-antenna when maximum penetration is required. It is a portable lightweight antenna with very high penetration. The SUBECHO-40 can be used in air-coupled and airborne applications.

This antenna is fully compatible with GSSI plug-in electronics: 769DA2, 778 and 766DA allowing mono- (one antenna) and bistatic operation (two antennas).

SUBECHO-70

The SUBECHO-70 is a smaller version of the popular SUBECHO-40. It is a portable lightweight antenna with high penetration and improved resolution.The SUBECHO-70 can be used in air-coupled and airborne applications.

This antenna is fully compatible with GSSI plug-in electronics: 769DA2, 778 and 766DA allowing mono- and bistatic operation (two antennas).

SUBECHO-150

This antenna is fully compatible with GSSI plug-in electronics: 769DA2, 778 and 766DA allowing mono- and bistatic operation (two antennas).
