As is well known, the directions-of-arrival (DOAs) can only be determined within an unknown rotational angle in this array model. However, the phase ambiguity has no impact on the identification of the spatial signature. Two auto-calibration methods are presented for spatial signature estimation. In our methods, the rotational DOAs and model error parameters are firstly obtained, and the spatial signature is subsequently calculated. The first method extracts two subarrays from the ULA to construct an estimator, and the elements of the array can be used several times in one subarray. The other fully exploits multiple invariances in the interior of the sensor array, and a multidimensional nonlinear problem is formulated. A Gauss–Newton iterative algorithm is applied for solving it. The first method can provide excellent initial inputs for the second one. The effectiveness of the proposed algorithms is demonstrated by several simulation results.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/4.0/).","subitem_rights_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"14248220","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1722929371688":{"attribute_name":"出版社版DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"10.3390/s150613899"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/s150613899","subitem_relation_type_select":"DOI"}}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"318360"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Cao, Xiang","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Xin, Jingmin","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"西尾, 芳文","creatorNameLang":"ja"},{"creatorName":"ニシオ, ヨシフミ","creatorNameLang":"ja-Kana"},{"creatorName":"Nishio, Yoshifumi","creatorNameLang":"en"}],"familyNames":[{"familyName":"西尾","familyNameLang":"ja"},{"familyName":"ニシオ","familyNameLang":"ja-Kana"},{"familyName":"Nishio","familyNameLang":"en"}],"givenNames":[{"givenName":"芳文","givenNameLang":"ja"},{"givenName":"ヨシフミ","givenNameLang":"ja-Kana"},{"givenName":"Yoshifumi","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"87","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10726/profile-ja.html","nameIdentifierScheme":"徳島大学 教育研究者総覧","nameIdentifierURI":"http://pub2.db.tokushima-u.ac.jp/ERD/person/10726/profile-ja.html"},{"nameIdentifier":"80253227","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?qm=80253227"}]},{"creatorNames":[{"creatorName":"Zheng, Nanning","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-08-26"}],"displaytype":"detail","filename":"sensors_15_6_13899.pdf","filesize":[{"value":"310 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2008651/files/sensors_15_6_13899.pdf"},"version_id":"8efca5d5-b7c2-47a2-ba2b-5a4c7bfb9c05"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"array signal processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"auto-calibration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parameter estimation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Spatial Signature Estimation with an Uncalibrated Uniform Linear Array","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spatial Signature Estimation with an Uncalibrated Uniform Linear Array","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"7","path":["1713853295607"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-08-26"},"publish_date":"2021-08-26","publish_status":"0","recid":"2008651","relation_version_is_last":true,"title":["Spatial Signature Estimation with an Uncalibrated Uniform Linear Array"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-01-24T04:32:48.596171+00:00"}
