Merging of optical and SAR data

Abstract

To get more information about an interesting area is to merge the image data from different sensor types. This poster shows an approach to merge optical image data and synthetic aperture radar (SAR) data. Usually, this is done by ortho-rectification, which means a transformation of the image’s projection plane to a geographic coordinate system. Unfortunately, the resampling of the slant range based image space of a space borne synthetic aperture radar (SAR) to such a coordinate system strongly distorts and therefore reduces its information content. To preserve maximum information extraction, this poster shows an approach to transform optical images into the radar image space.
