Just wondering, in case anybody knows - can this same technology ‘look’ under sand as well as ice?
It might be nice to check under the Sahara for anymore Egyptian ruins - maybe other places, too, such as the Tigris/Euphrates area....?
Looking for stuff under the Egyptian sand is going to be a one shot event and then banned if it has not already been banned. None of the vested parties not Hawas nor Lehner want anything that would discredit or challenge the accepted status quo and their income and chain of grants.
They have already successfully banned optically stimulated luminescence (OSL)/optical dating. Those tests returned dates which were too old for the standard time line and just played havoc with an area of archaeology which is already in chaos.
There are also possible very interesting stuff buried under the Nile delta mud ... however, most of the places where one might look in the ME or North Africa are just plain too dangerous due to the present Islamic infestation.
There’s a Long-Lost Paleo-River Beneath the Sahara Desert Nobody Knew Existed
excerpt
Skonieczny and her colleagues were able to identify the paleo-river using an orbital satellite system called Phased Array type L-band Synthetic Aperture Radar (PALSAR). Using microwave sensing, PALSAR can peer into several meters into the Saharan sands and detect the fossil water still flowing there.
