Kurzfassung

Three time series of dual-pol TerraSAR-X images have been acquired during the whole cultivation period for a rice site in Spain. Among different observations, the backscattering at HH and VV channels, and the HH/VV ratio at 30 degrees incidence has shown a temporal signature with a clear correlation with the development of plants during the vegetative and reproductive phenological phases. A physical interpretation has been provided for this response. Results provided by the dual-pol entropy-alpha decomposition and by the phase difference between copolar channels have been also introduced and preliminarily discussed. In addition, these images have demonstrated to be useful for discriminating rice fields from other types and also for detecting areas with irrigation problems inside the rice field.
