However, phase velocities estimated by conventional SAC methods such as band-pass filtered method or Fast Fourier Transform method were not precise if suitable band width was not selected for analysis. We proposed a new technique for SAC using autoregressive model which estimated spectra with high resolution becaus the best fitting model can be selected using AIC. We apply the new method to calculate phase velocities of microtremors which were observed at a ground of Morioka Technical High School with arrays. As a result, phase velocities calculated by the new method were continous with frequency although those calculated by the conventional methods were scattered. This indicates that SAC functions calcdated by the new method are estimated better than those by conventional SAC methods.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"61305","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMAMOTO, Hidekazu"}]},{"nameIdentifiers":[{"nameIdentifier":"61306","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OBUCHI, Takuya"}]},{"nameIdentifiers":[{"nameIdentifier":"61307","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAITO, Tokumi"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人物理探査学会"}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c)  1998 SEGJ"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0912-7984","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学工学部建設環境工学科"},{"subitem_text_value":"川崎地質（株）"},{"subitem_text_value":"岩手大学工学部建設環境工学科"}]},"item_16_version_type_27":{"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":"山本, 英和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小渕, 卓也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斎藤, 徳美"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"bt-v51n1p70-76.pdf","filesize":[{"value":"424.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bt-v51n1p70-76.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9865/files/bt-v51n1p70-76.pdf"},"version_id":"9058a1cf-1f0a-4aef-9b37-7f604b88518d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"spatial autocorrelation method","subitem_subject_scheme":"Other"},{"subitem_subject":"microtremor array observation","subitem_subject_scheme":"Other"},{"subitem_subject":"autoregressive model","subitem_subject_scheme":"Other"},{"subitem_subject":"S-wave velocity structure estimation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"微動アレイ探査における空間自己相関法の自己回帰モデルを用いた改良","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"微動アレイ探査における空間自己相関法の自己回帰モデルを用いた改良"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-13"},"publish_date":"2009-11-13","publish_status":"0","recid":"9865","relation_version_is_last":true,"title":["微動アレイ探査における空間自己相関法の自己回帰モデルを用いた改良"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:54:22.460433+00:00"}
