Statistical POLSAR image analysis is carried out for both X- and L-band data, based on a threecomponent scattering power decomposition method, where the decomposed components are surface scattering, doublebounce scattering and volume scattering components. From the results of the image analysis for the L-band POLSAR data acquired by Pi-SAR system, it is found that strong doublebounce scattering can be observed at the vicinity of the boundary region between water area and the surrounding emerged-plants area in early and middle summer seasons. To verify the generating mechanism of the double-bounce scattering, the Finite-Difference Time-Domain (FDTD) polarimetric scattering analysis is also executed for a simplified boundary model, which simulates the local boundary region around the lake and consists of lots of vertical thin dielectric pillars on a perfect electric conductor (PEC) plate or on a PEC and dielectric hybrid plate. Taking into account the polarimetric feature of the double-bounce scattering obtained by both the FDTD and POLSAR image analyses, one can distinguish the water area form the bush of the emerged-plants around the lake, even when the water area are concealed by emergedplants and/or floating-leaved plants. Consequently, it is found that by using the proposed approach, one can estimate the water area seasonal change for the lake and the surrounding wetland.","subitem_description_type":"Abstract"}]},"item_8_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers"}]},"item_8_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ap-s.ei.tuat.ac.jp/isapx/","subitem_relation_type_select":"URI"}}]},"item_8_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright(C)2006 IEICE"}]},"item_8_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sato, Ryoichi"}],"nameIdentifiers":[{"nameIdentifier":"168994","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yajima, Yuki"}],"nameIdentifiers":[{"nameIdentifier":"168995","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"19","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, Hiroyoshi"}],"nameIdentifiers":[{"nameIdentifier":"50","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-26"}],"displaytype":"detail","filename":"ISAP2006_3B1b-1.pdf","filesize":[{"value":"338.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ISAP2006_3B1b-1.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/30941/files/ISAP2006_3B1b-1.pdf"},"version_id":"6accaa2c-7ba7-45b1-abb1-6f814cee219b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Seasonal Change Investigation of Water Area in Lake Sakata Based on POLSAR Image Analysis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seasonal Change Investigation of Water Area in Lake Sakata Based on POLSAR Image Analysis"}]},"item_type_id":"8","owner":"1","path":["457","1822"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"30941","relation_version_is_last":true,"title":["Seasonal Change Investigation of Water Area in Lake Sakata Based on POLSAR Image Analysis"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T04:01:28.825437+00:00"}
