In this paper a new class of X--SAR products-- images with a geometrical resolution of 12.5m by 12.5m are introduced. A comparison with the standard 25m by 25m products is given. Despite of the enlarged amount of speckle these images show obviously a better 'quality' if geometric and not radiometric resolution is on demand. The new class of products supports recognition of man made structure and edge detection. Keywords: SAR Processing, High Resolution Imaging, Image Quality THE X--SAR MISSIONS Two Shuttle Radar Lab (SRL) missions with the SIR--C and X--SAR instruments have been conducted in April and October 1994. During these Space Shuttle flights more than 100 hours of raw data from all continents (excluding Antarctica) have been acquired in each channel. Various test sites have been acquired under completely different conditions. The German and Italian PAF are in charge of processing the X-- band data while JPL proceeds with the L-- and C-- band data. The acquisition parameters .
