Satellites Could Spot Buried Treasures
Satellites really could be used to spot ancient archaeological treasures buried underground, two researchers in Israel have shown.
Scientists had previously suspected that certain types of imaging system could look beneath the surface of the Earth under some circumstances, but no-one had the proof.
Dan Blumberg and Julian Daniels, of the Ben Gurion University, told New Scientist magazine how they were able to detect flat squares of aluminium which they had buried at different depths in the sand of the Negev desert.
The pair used radar sensors on board an aircraft.
"Now we have systematic proof. Buried objects can be detected from airborne systems," Dr Blumberg said.
