Abstract	Abstract : In this study, detection of icebergs that have various scattering characteristics aroundWilkinson glacier in West Antarctica is investigated using C-band fully-polarimetric RADARSAT-2SAR data. Various polarimetric analyses including Freeman-Durden decomposition, H/A/ @a decomposition, entropy (H) and anisotropy (A) method, and Wishart unsupervised classification, wereapplied for the RADARSAT-2 data used in this study. The polarimetric decomposition methods weresuccessfully classified most of the iceberg, yet some iceberg with similar intensity of volume andsurface scattering as sea ice were indistinguishable. Unsupervised classification with a combination ofthe polarimetric parameter, [1-H][1-A], gave a possibility to distinguish those unclassified iceberg.Key Words : Iceberg, West Antarctica, Polarimetry, RADARSAT-2, Classification� i�� ¤� A�²�×�²�i�O c A$ a8JMLJOTPO��B Þ±�o Ad Þ�×�i ¨ a��AE `U8��I�×�B�8� c��($��O�X3"%"34"5��D�io u a�?�³��eI� 4"3�W��3I Þ E �N a�uS�×�Ý�e8 E�³ Þ O�i��io u4"3�W�� Ax a�uS�×�i ¨ a�Ý�e�\oyW�Ý u��AE `�?8 u a�uS�×'SFFNBO�%VSEFO�EFDPNQPTJUJPO�)�"��@a EFDPNQPTJUJPO��O�;�FOUSPQZ� ) iBOJTPUSPQZ "��Ý�e�\��io u4"3W��D��(�3$ c8JTIBSU��E�)��(�e8 E�³N E4"3�W�� Ax Þ O�i��O�~��'SFFNBO�%VSEFO�)�"��@a EFDPNQPTJUJPO8I a�Ý�e�\7��D�B��\8\��( Þ ON�E c�B��: $ a ´�v��AE� Sx��AE8�>N�S�×�B�7�³��:N �i��E�v�) i"D a�o�uo Þ�aK ��o�u�3I a��E�)��(�e7I�Þ a�B��\8\�³�� Þ O�i
