POLARIMETRIC SAR SIGNATURE FOR CROP CHARACTERIZATION

In contrast to the widely used van Zyl received wave polarimetric signature, the Touzi scattered wave signature in term of the total power (S0), and the degree of polarization (p) is also helpful for target characterization. Although, the van Zyl polarimetric signature includes the contribution of S0, and p, the explicit consideration of the two scattered wave parameters (i.e., independent of the received wave polarization basis) can provide additional information about the target. Hence, in this study, we have used both the van Zyl received, and Touzi scattered wave information to characterize scattering from Paddy at a particular phenological stage with C- and L-band full polarimetric SAR data.
