Open Ground Penetrating Radar

I envision three modes of operation for this project:

1) Human carried. Good for hard to reach places, but labor intensive.

2) Unmanned ground vehicle. Good for large, easy to access areas. Long operating time.

3) Unmanned aerial vehicle. Possibly good enough for an initial survey. Short flight time.

I just got home from the Bring-A-Hack meetup at Pumping Station One in Chicago. It was very inspiring to see all the enthusiasm that people put into such a wide variety of projects!
