Since the Doppler shift is clearly different for ducted and non-ducted propagations, an existence of the duct can be easily detected. In case of the non-ducted propagation, the wave normal tends to direct within the resonance cone angle, where the electron temperature of the plasma is highly effective to the refractive index and therefore to the Doppler freguency shift. A feasibility of the deduction of the electron temperature from the observed Doppler shift is theoretically confirmed in this report.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124427000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"京都大学工学部"},{"subitem_text_value":"京都大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木村, 磐根"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 弘蔵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KIMURA, Iwane","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIMOT, Kozo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-23"}],"displaytype":"detail","filename":"SA0124427.pdf","filesize":[{"value":"422.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124427.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31519/files/SA0124427.pdf"},"version_id":"81d5f538-b165-42be-96ee-714baaedae7f"}]},"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":"EXOS-B搭載ダクトモニターと電子温度測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"EXOS-B搭載ダクトモニターと電子温度測定"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31519","relation_version_is_last":true,"title":["EXOS-B搭載ダクトモニターと電子温度測定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:57:43.764257+00:00"}
