摘要：

Feature extraction is very important for interpreting polarimteric SAR images. Compact polarimetric imaging mode has been provided as an experimental mode in ALOS/PALSAR-2 to enable wide swath coverages of more polarimeric observations compared to the conventional dual-pol modes. In this study, to explore more information from compact data, we propose a least squares (LS) method to estimate the parameters of surface, double-bounce, and volume scattering mechanisms. Verifications on ALOS/PALSAR-2 data show that significant features are preserved by the new method for surface characterisation.
