The launch of Sentinel-1A and Sentinel-1B initiated a new age in Synthetic Aperture Radar (SAR) systems for earth observation. For the first time, multitemporal SAR imagery from all over the world is freely available.
SAR images are an essential information source for monitoring and mapping wetlands since the SAR signals are able to penetrate through the vegetation and provide information about soil moisture characteristics and above-ground vegetation. However, vegetation type identification in wetlands using high temporal resolution SAR data requires more investigation.
