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 polarization (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.
