These two applications are based on the common technique, that is, null steering. This tutorial paper reviews the MUSIC algorithm which is one of the typical high-resolution techniques. Examining the eigenvector beam patterns, we demonstrate that the high-resolution capability is realized by steering nulls. The considerations will be useful for understanding the high-resolution techniques in the signal processing antennas. We then describe a modified version of MUSIC (Root MUSIC). We show the performance and robustness of the method. Furthermore, we introduce radar target identification and two-dimensional radar target imaging. These study fields are new applications of the signal processing antennas, to which a great deal of attention has been devoted recently.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3040","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040195219","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040195219"}],"names":[{"name":"菊間, 信良"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers","subitem_publisher_language":"en"}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8516","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10826261","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ogawa, Yasutaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13363","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuma, Nobuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3040","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040195219","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040195219"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-23"}],"displaytype":"detail","filename":"E78-B_1435.pdf","filesize":[{"value":"598.9 kB"}],"format":"application/pdf","license_note":"Copyright (c) 1995 IEICE　http://search.ieice.org/index.html","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/4381/files/E78-B_1435.pdf"},"version_id":"aac50905-172b-4cf0-8359-a545e2cf7932"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High-Resolution Techniques in Signal Processing Antennas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-Resolution Techniques in Signal Processing Antennas","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-06-25"},"publish_date":"2013-06-25","publish_status":"0","recid":"4381","relation_version_is_last":true,"title":["High-Resolution Techniques in Signal Processing Antennas"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-14T02:38:33.729192+00:00"}
