A-scope data from sounder with wide antenna beams include information on the scattering characteristics at the ice sheet surface, within the ice sheet itself, and at the bedrock sub-surface. Characteristics are modeled from the A-scope form by using expanded radar equations which allow determination of the roughness of the ice sheet and bedrock surfaces. Results indicate a strong dependence of backscatter from the ice surface with incidence angle and a weak dependence in backscatter from the bedrock.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003575","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":"AA10756213","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":"Communications Research Laboratory, Ministry of Posts and Telecommunications/National Institute of Polar Research/Institute of Low Temperature Science, Hokkaido University/Department of Applied Physics,Faculty of Engineering, Hokkaido University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-08-01"}],"displaytype":"detail","filename":"KJ00000035541.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035541","url":"https://nipr.repo.nii.ac.jp/record/3575/files/KJ00000035541.pdf"},"version_id":"781a4836-e02e-4f28-88b3-398b947d45a1"}]},"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":"Radio scattering characteristics of Antarctic ice sheet using airborne radio echo sounding data","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radio scattering characteristics of Antarctic ice sheet using airborne radio echo sounding data"}]},"item_type_id":"1","owner":"4","path":["526"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-08-01"},"publish_date":"1989-08-01","publish_status":"0","recid":"3575","relation_version_is_last":true,"title":["Radio scattering characteristics of Antarctic ice sheet using airborne radio echo sounding data"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:32:03.011362+00:00"}
