Ground-penetrating and Space-born Radar
The University of Notre Dame
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process.
This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

This is a introductory lecture on ground-penetrating radar and space-born radar, a classroom data classifying activity, and descriptions of field and extended activities.
This is used in a semester-long geophysics course for juniors, seniors, and beginning graduate students who have had no prior geophysics. Most are majors. Designed for a geophysics course
Skills and concepts that students must have mastered
have fulfilled the requirement of a year each of college physics and chemistry by the time they take this course. However, the material can be presented with just calculus (and the higher math deleted) fairly easily. They should be familiar with tectonics, surface processes, and some mineralogy/petrology.
How the activity is situated in the course
This is one week out of 3-4 devoted to Radar, usually early in a 15 week course.
Content/concepts goals for this activity
Understand and describe radar dependence on wavelength, roughness, and dielectric constant.
Plan and execute a ground penetrating radar field survey.
Higher order thinking skills goals for this activity
Students will be able to Interpret basic ground-penetrating and space-born radar images and compare them to visible/near-IR images.
Other skills goals for this activity
Description of the activity/assignment
Students are asked to do background reading before class. The lecture introduction included is presented, and then students do an group exercise sorting GPR and space radar images into image types and bands. They then plan and carry out a ground penetrating radar field survey, and download and interpret the results. They are asked to do several quantitative homework problems, and to retrieve and present (powerpoint) additional types of radar data. An extension exercise for higher level students is suggested using large data sets.
Determining whether students have met the goals
Evaluations of class group exercise, homework calculations, powerpoint presentation, and field project.
