Abstract :
This paper presents the comparison between the potential of SAR data in compact polarimetry (CP) and full polarimetry mode for snow detection. Eigenvalues based analysis and developed procedure have been used for this inter-comparison. It has been found over the part of rugged Siachen glaciated terrain, Indian Himalaya that dual polarization and compact polarization mode show-30% and-15% less capability than FP mode respectively.
