We have developed a new code to monitor and remove DC offsets. To obtain correct DC offset levels and noise levels, the offsets can be best removed using I/Q signals during the receive-only period, i.e., during each clear frequency search stage. We have implemented the new code in the current radar operating system, installed it at the SENSU Syowa radars, and have been obtaining and removing DC offset values continuously since October 2001.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006357","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11397422","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research/National Institute of Polar Research/National Institute of Polar Research/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2002-09-01"}],"displaytype":"detail","filename":"KJ00000047996.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000047996","url":"https://nipr.repo.nii.ac.jp/record/6357/files/KJ00000047996.pdf"},"version_id":"d83bf0ac-2b3d-4088-a632-c8f7c5c51c3a"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A new method for monitoring and removing SuperDARN radar DC offsets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A new method for monitoring and removing SuperDARN radar DC offsets"}]},"item_type_id":"1","owner":"4","path":["806"],"pubdate":{"attribute_name":"公開日","attribute_value":"2002-09-01"},"publish_date":"2002-09-01","publish_status":"0","recid":"6357","relation_version_is_last":true,"title":["A new method for monitoring and removing SuperDARN radar DC offsets"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:02:35.669558+00:00"}
