Dual Polarimetric Decomposition for Wheat Monitoring Using C-Band SAR Data

Abstract

The Synthetic Aperture Radar (SAR) time series using Sentinel-1 data has wide applications in crop monitoring. The wheat crop structurally followed a specific phenology, distinguishing it from other similar-looking plants. Polarimetric parameters such as wave entropy, wave anisotropy, and polarimetric decompositions such as Chandrasekhar decomposition using dual-pol data are sensitive to the structural behavior of the target. The time series profile of these parameters for the wheat growth stages is shown in this study. Wave entropy, Wave anisotropy, and Chandrasekhar decomposition parameters range from 0.4 to 0.7,0.5 to 0.8, and 0 to 0.2 respectively. © 2025 IEICE Electronics Society.
