• One of the main advantages of polarimetric radar data analysis is the possibility of separating and identifying contributions from different types of scatterers in the imaged terrain. To do this, the received scattering matrix is analyzed using various techniques to extract information about the scattering processes, referred to as "target decomposition". In the present study, full polarimetric L-band ALOS PALSAR data has been used to generate various decomposition techniques using RAT and PolSARpro software. Different Decomposition techniques like Freeman Durden, Eigen value/ Eigen vector, H/A/α and Moriyama decomposition have been considered for this study. The study area is a desertic terrain comprising of agricultural land with pieces of scattered waste lands over Nagaur District. With help of ERDAS Imagine software, training windows were marked and signatures of four land use classes were extracted based on target detection in the target decomposition theorems. Contingency matrix and class separability were evaluated for each decomposition technique. Outputs of the decomposition techniques were also analyzed for observing the accuracy of these techniques for each selected land use class. When considering the overall case, maximum accuracy of pixel classification and separability was observed in case of Eigen vector based decomposition, followed by Moriyama decomposition, Freeman Durden decomposition and H/A/α decomposition. This paper is thus an attempt to evaluate the various decomposition techniques based on separability and classification accuracies for proper utilization of Polarimetric SAR data.
