Drone-Borne Synthetic Aperture Radar for GPR Applications: Buried Pipe Inspection

A multiband polarimetric synthetic aperture radar was used to study subsurface piping under desert conditions. In Abu Dhabi, United Arab Emirates, a measurement campaign was performed using a drone-borne synthetic aperture radar to obtain microwave images in three frequency ranges: P, L, and C-band. Typical reflections from this environment are identified. Results show that the system is suitable for subsurface inspection of buried piping, particularly in L band.
