<abstract>
<p>Various urban targets (land use) from Ahmedabad city were chosen, followed by generation of
polarimetric signatures for each target using the developed tool. These polarimetric signatures were
then studied and analyzed in detail. An attempt has been to develop a Polarimetric Signature
Calculation and Visual Representation Tool assigned name &quot;POLSIC&quot;, to generate Co-polarized
and Cross polarized signatures, based on the calculation of Stokes Matrix and the backscattered
power at various ellipticity and orientation angles. The input parameters required for the developed
tool, are the amplitude and phase values of all the four polarizations, for each target using any
quadpol radar imagery. In this study, RADARSAT-2 imagery has been used to obtain the amplitude
and phase values of each target, in all four polarization states. Polarimetric signatures were
generated for various urban targets using the developed tool. Vegetated land, built up in the city,
built up within lake, and road were found to have an overall higher polarimetric response
(backscattered power) as compared to grass lawn, fallow land and minimum in case of water body.
Such Polarimetric responses were obtained due to factors like surface roughness and orientation of
the target with respect to the radar look angle. The shape of the signature also indicates the
scattering characteristics.</p>
