Sentinel-1 Synthetic Aperture Radar (SAR) characteristics on shoreline demarcation and shoreline change assessment along mandaikadu, south-west coast of India

Sentinel-1A is a dual-satellite sensor carrying C-band (λ=5.6cm), The images were acquired in dual-polarization modes; (i) VV (vertical transmit and vertical receive) polarization and (ii) VH (vertical transmit and horizontal receive) polarizations. The preprocessing of Level-II ground range detected (GRD) images from Sentinel-1 SAR was performed using the Sentinel application platform (SNAP) toolbox
