A sum and difference composite co-array is basically a combination of sum and difference co-arrays. Our configuration can realize higher degrees of freedom (DOF) with the sum co-array part at a calculation cost lower than those of the other sparse arrays. To further enhance the robustness of our proposed sum and difference composite co-array we design an optimal beam pattern by WSF based on the information of estimated DOAs. Performance of the proposed system and the DOA estimation accuracy of close-impinging waves are evaluated through computer simulations.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Institute of Electronics, Information and Communication Engineers  "}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1587/transcom.2019EBP3213","subitem_relation_type_select":"DOI"}}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.1587/transcom.2019EBP3213"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1587/transcom.2019EBP3213","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2021 IEICE"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8516","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University"},{"subitem_text_value":"Department of Electrical and Computer Engineering, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Iwasaki, Sho"}],"nameIdentifiers":[{"nameIdentifier":"38172","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Shogo"}],"nameIdentifiers":[{"nameIdentifier":"38173","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50212098","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50212098"}]},{"creatorNames":[{"creatorName":"Ichige, Koichi"}],"nameIdentifiers":[{"nameIdentifier":"35444","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10313470","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10313470"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-01-06"}],"displaytype":"detail","filename":"e103-b_10_1147.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"e103-b_10_1147.pdf","url":"https://ynu.repo.nii.ac.jp/record/10870/files/e103-b_10_1147.pdf"},"version_id":"70f19152-638e-4187-ad82-904dd4fe4217"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"array antenna","subitem_subject_scheme":"Other"},{"subitem_subject":"adaptive beamforming","subitem_subject_scheme":"Other"},{"subitem_subject":"direction of arrival estimation","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":"DOA-Based Weighted Spatial Filter Design for Sum and Difference Composite Co-Array","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"DOA-Based Weighted Spatial Filter Design for Sum and Difference Composite Co-Array"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-01-06"},"publish_date":"2021-01-06","publish_status":"0","recid":"10870","relation_version_is_last":true,"title":["DOA-Based Weighted Spatial Filter Design for Sum and Difference Composite Co-Array"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T18:17:39.598024+00:00"}
