Abstract

This study showcased the capabilities of dual-pol synthetic aperture radar (SAR) remote sensing dataset to characterize Rhizophora and Avicennia types of mangroves in Pichvaram, India. The focus of the study was to utilize the Sentinel-1A derived polarimetric coherence pattern in the rotation domain to differentiate mangrove types. The polarimetric coherence for both species was generated at a specific interval in the rotation domain and analyzed for different rotation angles for various seasons in 2019. Both the mangrove types demonstrated the similar type of polarimetric coherence pattern with differences in the range of values. The discrimination between the species was investigated temporally, revealing the importance of the season and suitable interval of the rotation angle for mangrove type characterization.
