Timely and accurate information about various habitats of a wetland ecosystem is necessary for the assessment, monitoring and management of a wetland. In this article, the state-of-the-art Polarimetric Synthetic Aperture Radar (PolSAR) data have been analysed to characterize various components of a wetland ecosystem. SAR polarimetry has received negligible attention in India, mostly owing to lack of data over the Indian sub-continent. With a recent DLR-ESAR (Experimental-SAR) flight over India, it was possible to conduct a detailed, planned experiment to explore the potentials of SAR polarimetry. This study has been carried out using fully polarimetric, multi-frequency DLR
