A Study on the Polarimetric Properties of Various Features using SIR-C Data

By KS RAO, YS RAO and HKA JASSAR

Abstract

Spaceborne Imaging Radar (SIR-C) data acquired over Gujarat, India in 1994 were processed and analysed using differnet techniques applicable to polarimetric SAR data such as polarization signatures, polarization index, decomposition of the signal and polarization phase difference and limited groundtruth data. It has been observed that multi-frequency polarimetric data enhances the potential of retrieving geo-physical parameters. The polarization signatures are found to vary with the nature of the target. Target decomposition of the returned signal will be useful for the classification of various features. Polarization Phase Difference (PPD) gives good information about the vegetation parameters

Topics: polarization phase difference, polarimetric properties, sir-c, polarization signature, corner reflectors
