This thesis investigates the effect of several algorithms for high dynamic to low dynamic range compression applied to SAR-images. In this case the dynamic range is the range of possible gray values or colors contained in an image. Therefore the first part will cover the current problem. Then techniques for both radar and optical image acquisition are explored. During this exploration technical and physical foundations for the different systems will be explained. Visual differences between the obtained results will also be dicussed. The next part presents several different algorithms for compressing HDR data. In the course of this presentation the implementation of a masking algorithm will also be discussed. Finally, optimal parameters for each of the previously described methods are evaluated and their results will be compared to eachother.
