Abstract

From May 11 to July 31, 1992 the CLoud Experiment OberPfaffenhofen and TRAnsports (CLEOPATRA) took place as a field experiment contribution to the global energy and water cycle experiment (GEWEX/IGBP). The DLR Institute of Radio frequency technology participated with its experimental SAR system (E-SAR) in X-, C-, and L-band, HH and VV polarisations to investigate microwave backscattering mechanisms of agricultural crop types in dependence of multi-temporal ground truth observations during the growing season. The first two flying dates are compared and the differences for the beginning of the growing season investigated
