Instead of Dropping Bombs, Can Drones Locate Unexploded Ones?

I realize it's pedantic, but the title is actually inaccurate. The vehicle(s) in questions aren't actually "drones"; the term drone implies fully autonomous use. The accurate term is "Unmanned Aerial Vehicle" (UAV) or "Remote Piloted Vehicle" (RPV).

This is also not exactly new technology. The United States military has been using Synthetic Aperature Radar (SAR) in small UAVs (hand-launched) to perform similar tasks identifying IEDs for at least the last year.
