Sentinel 1 Image Character Analysis for Mapping Wetland Vegetation

摘要

Wetlands are an important natural resource that requires monitoring. Time-series Sentinel 1A (C-band) for Radar images are used to investigate the spatial-temporal image characters variation for different wetland vegetation in growing season. Backscattering coefficients, scatter mechanisms will be selected from the Sentinel 1A to study the scattering scheme and structure information of the wetland vegetation. The results showed that by backscatter coefficients VH polarization is better to investigate the wetland vegetation than VV polarization. Spatial-temporal scatter mechanisms could be a good way for the dual-polarization Radar to describe the different scatter scheme of the wetland vegetation during different growing statues of vegetation communities.
