The article highlights the results of a study carried out to understand the Synthetic Aperture Radar (SAR) response to the second most important fibre crop of India i.e. Jute at C and L band frequency and at multiple polarizations. Methodology has been well established to classify jute crop using 3-date multitemporal HH SAR data and is being used for national level forecast in India. Performance comparison of single polarization (HH) multi-date versus dual-polarization 2-date data from Radarsat (both dual-pol HH/HV and quad-pol) was evaluated. Three-date HH polariza-tion (May, 05, May 29 and June 22) data had results comparable to two-date HH/HV data with around 90% accuracy. Correlation between backscattered signals and crop height shows that L-band signal has high correlation with crop height particularly in the peak or advanced crop growth stage as compared to C-band. Also backscatter variation with percent area cover has been investigated. Both plant height and area cover show stronger dependence to cross-polarization backscatter. Biophysical parameters viz. crop height and vigour map has been generated which will aid in monitoring growth and yield potentials.
