Abstract

Summary

Recent advances in timing and control technology have allowed the development of multi-concurrent receiver Ground Penetrating Radar (GPR) systems. These types of system enable rapid acquisition of Wide-Angle Reflection and Refraction (WARR) data and have the potential to provide a wide range of benefits, including improved velocity models. However, the high volume of data that can be generated, as well as the fact that these systems are new and continually being developed, demands research and automation of new processing workflows.

Numerical modeling is gradually becoming a standard approach in GPR for testing new processing schemes/algorithms and guiding interpretation of real data. Nevertheless, simulations can require detailed models of antennas, targets, and structures, which can be time-consuming to create programmatically.

In this work, we demonstrate a graphical user interface (GUI) tool for rapidly designing and building complex geometries that can be used in numerical simulations for GPR. We then use this toolset to generate realistic WARR data to test automatic first break/time-offset correction algorithms we have developed. These algorithms form the initial steps of our workflow for processing WARR data.
