一般注記ALOS PALSAR quadpol data acquired over several test sites of India were processed and analyzed for soil moisture mapping and classification. PolSARpro software and some programs developed by us were used for the processing of the PALSAR data. For soil moisture mapping, Dubois et al., Oh et al, and X-Bragg models were used. Dubois et al. model overestimates soil moisture as compared to Oh et al. model. It may be due to lower incidence angle at which the PALSAR data were acquired. As we do not have ground truth data synchronous with satellite passes, we just compared the inversion models and also the variation of soil moisture with time. We have observed variation in soil moisture in different months. In addition to soil moisture retrieval, PALSAR data were classified using different polarization and frequency combinations with recent available data. For Mumbai test area, fully-pol, dual (HH, HV) and (HH, VV) combinations gave almost same accuracies Lowest accuracy was observed for dual (HH,VV) intensity combination. PauliRGB and classified images give a lot of details about various land features. Backscattering properties of various land features using ALOS PALSAR data were also studied and compared with SIR-C and ENVISAT ASAR data.
