3 Month’s Online Course on Ground Penetrating Radar

The incorrect and inappropriate use of GPR has over the years caused a great deal of damage to its reputation as a bona fide and reliable technology. The objective of this course on GPR is to make the participants familiar with basic as well advanced data acquisition, data processing and interpretation techniques to derive maximum amount of information from data collected. After completing this course, user should be able to collect the GPR data, carry out basic as well as advanced data processing of data and interpret the results in a range of application areas.

The program will enable the participant to derive maximum information from GPR data and help them design the right GPR investigation program for a particular project requirement. It will also enable them to choose the right combination of antennas for varied geological conditions and resolution requirements. The minimum outcome of the workshop will be:

  1. Learn how to determine whether GPR will be suitable for a particular project objective
  2. Learn how to design GPR survey to get maximum information
  3. Learn how to choose various parameters during data acquisition
  4. Learn how to carry out simple in-field processing of data
  5. Learn how to carry out advanced processing to minimise noise and extract maximum information from GPR data
  6. Learn use and theoretical aspects of various filters, migration, corrections etc.
  7. Learn how to carry out 3D processing of data
  8. Learn to conduct QC checks on GPR data and results obtained through GPR contractors
  9. Application specific training on:
  10. Utility detection and mapping
  11. Concrete inspection (voids, delamination, rebar etc.)
  12. Pavement inspection (thickness of various layers etc.)
  13. Void detection
  14. Archaeology
  15. Any other topic/ application of interest of participants.
  16. Numerous practical tips for effective GPR utilization based on 3 decades of experience.
