However, when meteorological and maritime conditions are bad, or when the aspect angle of a small ship changes, it may become difficult to obtain a radar image of the small ship. Therefore, safe navigation is not assured. So, the measurement of a radar cross section of Nansei-maru was carried out. The results obtained in this study were as follows : 1. A refracting point between 1/R^4 and 1/R^8 attenuation curves existed at 3945m. 2. The effective height of radar wave reflection was measured at 2.46m from the surface of the sea. 3. The radar cross section was largest, 1790m^2, when the beam faced the radar antenna, and was smallest, 130m^2, when the bow was toward the antenna. The value decreased about 10 dB, when it shifted at 30° from the beam direction. In addition, the value of the stern direction was larger than that of the bow direction.", "subitem_description_type": "Other"}]}, "item_7_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "101642", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "マツノ, ヤスヒサ"}]}, {"nameIdentifiers": [{"nameIdentifier": "101643", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ヒガシ, マサタカ"}]}, {"nameIdentifiers": [{"nameIdentifier": "101644", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ハバノ, アキマサ"}]}, {"nameIdentifiers": [{"nameIdentifier": "101645", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "マエムラ, トモヒロ"}]}]}, "item_7_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "101646", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Matsuno, Yasuhisa"}]}, {"nameIdentifiers": [{"nameIdentifier": "101647", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Higashi, Masataka"}]}, {"nameIdentifiers": [{"nameIdentifier": "101648", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Habano, Akimasa"}]}, {"nameIdentifiers": [{"nameIdentifier": "101649", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Maemura, Tomohiro"}]}]}, "item_7_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "鹿児島大学"}]}, "item_7_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0453087X", "subitem_source_identifier_type": "ISSN"}]}, "item_7_source_id_9": {"attribute_name": "NII書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00040498", "subitem_source_identifier_type": "NCID"}]}, "item_7_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "660", "subitem_subject_scheme": "NDC"}]}, "item_7_subject_20": {"attribute_name": "NIIsubject", "attribute_value_mlt": [{"subitem_subject": "自然科学", "subitem_subject_scheme": "Other"}]}, "item_7_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマダイガク"}]}, "item_7_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_7_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_7_version_type_14": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "松野, 保久"}], "nameIdentifiers": [{"nameIdentifier": "101638", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "東, 政能"}], "nameIdentifiers": [{"nameIdentifier": "101639", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "幅野, 明正"}], "nameIdentifiers": [{"nameIdentifier": "101640", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "前村, 知宏"}], "nameIdentifiers": [{"nameIdentifier": "101641", "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": "2016-10-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00004175583.pdf", "filesize": [{"value": "496.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 496300.0, "url": {"label": "KJ00004175583.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/3304/files/KJ00004175583.pdf"}, "version_id": "e99b8001-5b66-45e9-b847-e241f202e12d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Radar cross section", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Reflection strength", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Fishing training ship", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "漁業練習船南星丸のレーダ有効反射面積", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "漁業練習船南星丸のレーダ有効反射面積"}]}, "item_type_id": "7", "owner": "3", "path": ["40", "4602"], "permalink_uri": "http://hdl.handle.net/10232/723", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-03-04"}, "publish_date": "2015-03-04", "publish_status": "0", "recid": "3304", "relation": {}, "relation_version_is_last": true, "title": ["漁業練習船南星丸のレーダ有効反射面積"], "weko_shared_id": 3}
