Abstract :
The authors use a new SAR technique for measurement of terrain slopes in the azimuthal (along-track) direction for correction of terrain slope-related polarimetric effects in SAR surface roughness, or soil moisture, inversion studies. A second goal is determination of the sensitivity of a circular polarization correlation function for the measurement of terrain slopes and surface roughness
