Advanced Survey Methods

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

Multi-channel Surveys

  • CMP: Common midpoint (CMP) surveys for subsurface velocity measurements and seismic-style trace stacking.
  • WARR:  Wide-angle reflection and refraction (WARR) surveys.
  • Borehole:  Subsurface measurements in boreholes
  • Transillumination: Direct one-way transmission through an object to extract travel time, amplitude and dispersion information.

pulseEKKO PRO is designed to meet the needs of GPR professionals, addressing a wide range of GPR applications.

  • The operating bandwidth is selectable from 12.5 MHz to 1000 MHz to optimize the system 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.
  • The selected components can exploit many deployment configurations available for practical field operation.
  • Data are acquired in Sensors & Software’s industry standard format for analysis with a range of processing and visualization software products.

pulseEKKO PRO is a configurable product.

pulseEKKO PRO components

Starting from a common control center, assemble the pulseEKKO components into a system best suited to your GPR application. Pick the antenna or transducer that provides the desired operating bandwidth.

  • Interchangeable antennas with bandwidths of 12.5, 25, 50, 100 and 200 MHz use fibre optic linked transmitter and receiver electronic modules.
  • Bandwidths of 250, 500 and 1000 MHz are provided by shielded transducer sets. Transducers are units which have antennas and electronics assembled into a monolithic package to optimize performance.
  • Several antennas or transducer sets can be used concurrently when using a multichannel adapter
