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", "download_preview_message": "", "file_order": 0, "filename": "ISAP2006_3B1b-1.pdf", "filesize": [{"value": "338.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 338500.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/21363", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-02-19"}, "publish_date": "2013-02-19", "publish_status": "0", "recid": "30941", "relation": {}, "relation_version_is_last": true, "title": ["Seasonal Change Investigation of Water Area in Lake Sakata Based on POLSAR Image Analysis"], "weko_shared_id": 2}
