An Adaptive Formulation: Radar Vegetation Index and Scattering Complexity

This study introduces two adaptive scattering descriptors for analyzing SAR data: (1) Radar Vegetation Index and (2) Scattering Complexity. The term “adaptive” highlights their flexibility, as these methods can be applied seamlessly to full-, dual-, and compact-polarimetric SAR data, ensuring suitability for diverse applications. These descriptors are evaluated using temporal Radarsat-2 data to analyze the growth stages of paddy in Vijayawada, India. The descriptors reveal interesting behaviors in the crop's growth dynamics, capturing key variations in scattering properties and vegetation structure at different stages.
