514 Ground-Penetrating Radar—Principles, Practice, and Processing
Ground penetrating radar (GPR) is a technology that uses radio waves to image into the subsurface to detect buried objects and boundaries. It has found widespread use in geology for more than 40 years for mapping geological structure and stratigraphy as well as groundwater and mineral exploration. Until recently, GPR systems were complicated to use and required extensive training for proficiency. Newer systems have simpler designs and user interfaces that allow users from many diverse scientific communities to adopt the technology for their particular problems and challenges. This course covers a bit of everything about GPR. The classroom agenda covers basic GPR theory, instrumentation, and survey design. The field portion takes the class outside to collect some data, including GPR cross sections integrated with GPS and a grid survey over a rectangular area of about 15 × 15 meters. Afterward, we will return to the classroom, and the instructor will transfer the data from the GPR system to the computer and plot the data as cross sections, 2D depth slices, and 3D cubes. At the same time, we will discuss principles of interpreting GPR data and how to present GPR data effectively for scientific papers and reports. GPS integration and displaying data in Google Earth is also covered. Case studies are presented to expose students to data from other application areas.
