Comparing sea ice areas identified within quad-polarimetry high-resolution SAR satellite scenes with the same areas in dual-polarimetry medium resolution SAR scenes
This thesis compares polarimetric features from quad-polarimetric (quad-pol) SAR (synthetic aperture radar) data and emulated dual-polarimetric (dual-pol) SAR data to investigate the information captured over sea ice areas located in the Barents Sea. The polarimetric features of entropy (H) and mean...

This thesis compares polarimetric features from quad-polarimetric (quad-pol) SAR (synthetic aperture radar) data and emulated dual-polarimetric (dual-pol) SAR data to investigate the information captured over sea ice areas located in the Barents Sea. The polarimetric features of entropy (H) and mean alpha, and the H/mean alpha-plot is compared, as well as the cross-polarizarion ratio and the damping ratio. It is shown that the interpretation of H, mean alpha, and the H/mean alpha-plot from emulated dual-polarimetric HH/HV data are not consistent with conventional interpretation of H, mean alpha, and the H/mean alpha-plot. The cross-polarization ratio and the damping ratio yielded promising results, and it was shown that for the data utilized in the thesis constituents of a given size can be separated from its surroundings in the emulated dual-polarimetric HH/HV data. |
