Seeing the Black Forest by ERS-1 and AIRSAR : A comparison
During 1991 the Black Forest, Germany, was surveyed by two unique SAR systems: the C-band SAR on board the ERS-1 and the polarimetric SAR on board the AIRSAR. Although the two sensors presented sensible differences in the basic imaging characteristics, the collected images were useful in the study of the temporal evolution of the radar backscattering from forested and unforested areas of the region. The forest return showed a dynamic range of about 5 dB over the seven months period, but in the October survey the range was reduced to about 2 dB. The unforested areas, either agricultural fields or clear cut areas, showed a large variation over the observed period with the result that the discrimination forest/not-forest was not always possible.
