In this method, an accurately controlled continuous signal is transmitted and the transfer function of the transmitted and the received electromagnetic fields is observed. Because the transfer function is required to be decomposed to extract information of electromagnetic structure, we here developed such a processing technique. We studied the case of a horizontal structure consisting of isotropic homogeneous layers. We introduced a ray model to describe the transfer function, and then applied an AR (autoregressive)-type model to describe the ray model as a discrete linear system. We further developed a practical algorithm to estimate the parameters of the AR-type model. The present technique is demonstrated to work well in a simple numerical experiment, and we could estimate electric structure easily using the decomposed transfer function.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126491","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yokoyama, Yukiko"}]},{"nameIdentifiers":[{"nameIdentifier":"126492","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kumazawa, Mineo"}]},{"nameIdentifiers":[{"nameIdentifier":"126493","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakajima, Takahiro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032640","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"核燃料サイクル開発機構東濃地科学センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"横山, 由紀子"}],"nameIdentifiers":[{"nameIdentifier":"126488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊澤, 峰夫"}],"nameIdentifiers":[{"nameIdentifier":"126489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島, 崇裕"}],"nameIdentifiers":[{"nameIdentifier":"126490","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0753004.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0753004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32640/files/ji0753004.pdf"},"version_id":"9c854549-9956-4298-85ca-c60f5fc8c81d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electromagnetic sounding","subitem_subject_scheme":"Other"},{"subitem_subject":"controlled source method","subitem_subject_scheme":"Other"},{"subitem_subject":"ray","subitem_subject_scheme":"Other"},{"subitem_subject":"decomposition","subitem_subject_scheme":"Other"},{"subitem_subject":"autoregressive","subitem_subject_scheme":"Other"},{"subitem_subject":"statistical modeling","subitem_subject_scheme":"Other"},{"subitem_subject":"frequency domain","subitem_subject_scheme":"Other"},{"subitem_subject":"ACROSS","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":"射線モデルと自己回帰型のモデルを組み合わせた電磁場伝達関数の分解方法 : 水平成層構造の場合","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"射線モデルと自己回帰型のモデルを組み合わせた電磁場伝達関数の分解方法 : 水平成層構造の場合","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4650","4652"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32640","relation_version_is_last":true,"title":["射線モデルと自己回帰型のモデルを組み合わせた電磁場伝達関数の分解方法 : 水平成層構造の場合"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:18.136461+00:00"}
