Temporal analysis of different crops using quad-pol RADARSAT-2 data

The objective of this study is to understand the temporal characteristic of cotton, sugarcane, banana and rice crop using C-band quad pol RADARSAT-2 data. Temporal response of these crops was analyzed using H/A/α and model based Freeman-Durden decomposition. Results of this preliminary study indicate that the (Entropy, anisotropy α and α1) parameters are sensitive to crop growth stages and can be used for crop mapping and monitoring purpose. The three basic scattering mechanisms (surface, volume and double-bounce) and H/A/α parameters obtained from these decompositions found suitable to distinguish between crop types and their temporal sensitivity.
