Abstract :
A comparative study of data acquired by two different airborne synthetic aperture radar (SAR) sensors from the same site is presented. External, ground-target-based calibration has been performed on the NASA/JPL DC-8 SAR C-band data and the DLR E-SAR C-band data collected over the DLR test site in Oberpfaffenhofen. The consistency of both the polarimetric and radiometric calibration parameters derived from different tracks indicates the stability of DC-8 SAR system during the campaign. Radar cross-sections and backscattering coefficients measured from different tracks under different incidence angles emphasize this stability
