Abstract:
This paper uses RADARSAT-2 quad Polarimetric Synthetic Aperture Radar (PolSAR) and TerraSAR-X dual polarimetric SAR data to monitor agriculture crop growth stages. Two RADARSAT-2 Fine Quad Wide (FQW) beam modes FQ2W and FQ10W, each of which has 5 sets of data, and 13 sets of Stripmap TerraSAR-X data were used in the study. Both RADARSAT-2 and TerraSAR-X PolSAR data were acquired in summer 2012 outside of Winnipeg, Manitoba, Canada. The study was carried out for two crop types: canola and wheat, each containing 5 regions of interest from ground truth crop classification map in the image scene. Polarimetric features such as differential reflectivity bands ratio, entropy, anisotropy, alpha angle and lambda were evaluated for these two crop types. The results from both RADARSAT-2 and TerraSAR-X data were compared and they demonstrated clear correlation between crop growth stages and polarimetric parameters. It is observed that entropy, lambda and differential reflectivity from both data have similar responses to crop growth stages in their common coverage period. The results were also validated using ground truth information.
