Types of secondary radar image products based on multiple radar images and digital 
  
Type of Product 
1. 
Ortho-Image 
False color from multiple 
ortho images. 
Simulated radar image 
Radiometrically rectified image 
False color from multiple radio- 
metrically corrected images. 
Stereo-ortho images from one 
single image 
Stereo-ortho images from two 
source images 
Comment 
Geometrically rectified black and white image to fit a 
map. 
Use three geometrically matched ortho- images 
Use of DEM to predict the geometry and radiometry of 
a radar image, based only on terrain slope and assumed 
backscatter of surface cover. 
Difference image between simulated and real radar 
images. 
Use three radiometrically corrected images. 
Create an image pair of which one is geometri- 
cally corrected (see 1), the other is the same radar 
image but has artificially introduced relief-displacement 
(so-called "stereo-mate"). 
As in item 6, but the "stereomate" is produced 
from a second overlapping radar image.
