Abstract

The authors present a method for improving relief reconstruction
from SAR stereo images, relying on preprocessing of input data with an
optimal filter. This filter strongly reduces speckle noise and enhances
relief structures, leading to better matching results. The method was
tested using X-SAR data of a mountainous site whose DEM was available
for control
