The differentiability of surfaces on Radar imagery is dependent on the parameters of the imaging system such as wavelength, polarisation, resolution, as well as on soil characteristics, geomorphology, and the geometric conditions during imaging. rn this research, to study the effects of pixel size on geological mapping using C-band data, several images of different resolutions have been simulated from an E-SAR airborne radar image acquired by the German space agency, Deutsche Luft und Raumfahrt (DLR).
