pulseEKKO®

pulseEKKO® GPR systems provide unparalleled performance with a wide-range of frequencies for applications ranging from deep mineral exploration and glaciology to high-resolution geotechnical investigations and concrete imaging.

System Overview

pulseEKKO® is designed to meet the needs of GPR professionals, addressing many GPR applications.

• The operating bandwidth is selectable from 12.5 MHz to 1000 MHz to optimize the spatial resolution required by target size and exploration depth.
• The fully bistatic design enables variable antenna offsets and orientations for advanced survey types such as multi-offset, transillumination and multi-polarization.
• Low system noise paired with high-accuracy digital acquisition directly at the receiving antenna results in unprecedented depth of penetration.
• Many deployment configurations are available for practical field operation.
• Data are acquired in Sensors & Software’s industry standard file format for analysis with a range of processing and visualization software products.

Antennas & Transducers Overview

Antennas & Transducers Overview

Applications

• Geological stratigraphy: Profile subsurface stratigraphy, structure and the bedrock surface
• Mining & Quarrying: Detect changes in rock type, fractures, faults and joints for safety and resource development in underground mines
• Geotechnical & Environmental: Map depth to bedrock, detect sinkholes, locate underground storage tanks (USTs) as well as septic systems, drainage systems on golf courses and farms
• Forensics & Archaeology: Law enforcement uncover buried caches of drugs, money, weapons and clandestine graves. Archaeologists image underground artifacts, tombs and the foundations of ancient structures
• Glaciology, Ice & Snow: Measure the thicknesses and image the internal structure of glaciers and ice sheets for polar ice-cap and climate change research. Measure snow depth for water resource management and ice thickness for ice road safety.
• Structure assessment: Assess the interior of concrete and pavement for asset management and maintenance planning

Advanced Survey Methods

As well as traditional reflection surveys, pulseEKKO’s bistatic antennas allow for variable antenna separations – ideal for CMP, WARR, multi-fold and transillumination surveys.

CMP

Common midpoint (CMP) surveys for subsurface velocity calculations, water content measurements and seismic-style trace stacking.

WARR

Wide-angle reflection and refraction (WARR) surveys; an effective tool for advanced GPR research projects.

Borehole

One-way measurements between boreholes and borehole-to-surface measuring velocity and attenuation; providing a unique option for using GPR in electrically-conductive soils.

Transillumination

Direct one-way transmission through an object to extract travel time, amplitude and dispersion information.

Multi-channel Surveys

pulseEKKO® is a configurable product. pulseEKKO® components can be used as building block for larger, more advanced systems. For example, several antennas or transducer sets can be networked together using the SPIDAR® hardware.
