Temporal multiparameter airborne DLR E-SAR images for crop monitoring - summary of the CLEOPATRA campaign 1992

Kurzfassung

Multitemporal X-, C- and L-band data from 8 dates and three ERS-1 images are analyzed in regard to the influence of changing plant backscatter constituents and to investigate the impact of increasing ground comver (biomanss) in the different wavelengths on soil moisture mapping. Backscatter curves of four crops are shown, which indicate the possiblitiy for crop monitoring and preferred times for crop classification. Detection of soil moisture chnages is only possible with L-band and only under grain crops. Maximum Likelihood classification allowed identification of the crop types with accuracies of up to 84 %, when a temporal multifrequency data set was used.
