Radar Remote Sensing of the Sahara Landscape

Inhalt:
It has been 30 years since the discovery of buried river valleys in the eastern Sahara with the first Shuttle Imaging Radar. Since then, studies have continued with SIR-B and SIR-C as well as other radar systems. In addition, old lake shorelines have been found using SRTM topographic data and other satellite images. All of these studies paint a picture of wetter climates in the Sahara’s past, a fact known to archaeologists, who have found evidence of human occupation along the shores of the lakes and rivers at various times over the past few hundred thousand years.
