【 摘 要 】

Rice areas in India are being mapped for acreage estimation using Synthetic Aperture Radar (SAR) data under forecasting agricultural output using space, agrometeorology and land-based observations (FASAL) program for over a decade now. Under this study, an attempt was made to segregate rice areas based on variety in parts of Punjab state. Data acquisition was done at critical stages of rice growth. The shift in transplantation in temporal domain and difference in canopy volume formed the basis of characterization of rice crop into two different varieties namely aromatic and non-aromatic. Multitemporal HH polarization data along with rate of change of cross polarization ratio (HH/HV) from July to September 2011 was used. The aromatic rice could be separated from normal rice with 91% accuracy.
