Shuttle Imaging Radar-A image (black & white strip) integrated with a Landsat image of the Sahara Desert in the southeastern region of Egypt. The comparision (see E620/171) was designed to show the different details obtained by the two imaging techniques. The radar image penetrates the surface deposits of windblown sands & reveals drainage channels & bedrock features below. These are not visible on the Landsat image. Using radar to penetrate the land surface is only possible in arid regions since soil moisture reduces the penetration of the beam | |
