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.

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.

Digital Video Logger (DVL)

DVL-500P

The latest evolution of pulseEKKO® – the DVL-500P data logger-has many features to make GPR surveys easier and your time in the field more efficient.

DVL Features

The digital video logger (DVL) has a high-resolution, sunlight-visible, touch screen and an intuitive user interface for efficient data collection. Easily adjust survey parameters including survey type, time window, step size, and stacking to optimize your GPR survey. For advanced surveys, easily control the antenna geometry and triggering method.

Depth slicing

Collect grids of data and view depth slices right in the field.

Map view

Display a plan map view of grids. Using external GPS, display a plan map view of the complete survey, including field interpretations and flags added during data collection.

Wi-Fi mini-reports

Email a report of line, depth slice or map view data to your customers or colleagues.

USB data transfer

Project data is easily exported to USB for post-processing.

Save configurations

Easily setup, name and save multiple configurations on the DVL to increase efficiency in the field.

Multi-language

Multiple interface languages on DVL including: English, French, German, Spanish, Japanese, Simplified Chinese, Farsi, Russian, Arabic.

Low Frequency Antenna Electronics

The antenna electronics package contains fibre optic–linked, battery-powered transmitter and receiver electronics modules. The receiver provides full digital data acquisition at the receiving antenna. Fibre optics provides the high performance needed for low frequency deep GPR sounding. The antenna electronics have quick snap–on assemblies to support 12.5, 25, 50, 100 and 200 MHz bandwidth antenna sets.

Receivers

pulseEKKO® has two receiver options, the pulseEKKO® PRO (Model 1600) and the pulseEKKO® Ultra (Model 3200).

pulseEKKO® PRO Receiver – Tested by time, the pulseEKKO® PRO Receiver delivers clean, high-quality data for all low frequency GPR applications. For over a decade, this receiver has allowed GPR professionals to collect data on the most remote corners of the earth. The superior data it produces has been the backbone of countless published papers and professional reports.

pulseEKKO® PRO (Model 1600)

pulseEKKO® Ultra Receiver – The Ultra Receiver uses the latest in GPR technology to allow users to see up to 2 times deeper. This receiver is fast enough to stack GPR traces thousands of times lowering the noise floor so weaker, deeper GPR signals are detected. The Ultra Receiver stacks thousands of times, allowing GPR practitioners to see GPR signals 100 times smaller than before. High stacking increases the dynamic range of the data from 16-bit to 32-bit.
