Multiple Incidence Angle SIR-B Experiment Over Argentina: Generation of Secondary Image Products

Original radar images may be geometrically and radiometrically distorted. This may be a particular problem when multiple angle imagery is analyzed and there is topographic relief in the area of interest. This paper describes a set of techniques designed to combine a multiple angle radar data set with a digital terrain elevation model, to generate a set of new images called secondary image products. These new images are geometrically rectified radar ortho-images, radiometrically rectified images, and stereo ortho-images. These secondary images can then reliably be used for thematic interpretation.
