To illustrate the characteristics of radar data, I have assembled as much radar data as I could get my hands on of Death Valley California. Please take a look at how different radar instruments (and different wavelengths and polarizations) "see" this interesting geological field site.
In addition, I have also assembled example images from different instruments, overlapping somewhat with the above.
To see the advantages of a multichannel radar system over a single channel radar system, I show here how a nice color image of the Kliuchevskoi Volcano in Russia was constructed from three black and white images corresponding to data from three different radar channels. ( I also compare this with the low resolution survey image available at the Eros Data Center (EDC), and with a Space Shuttle optical photo that was taken at the same time the radar image was obtained) (If you autoload images, you will have to load about 750K)
