The study contributes to the design of an efficient microwave sensor. For this purpose, experimentally observed data was utilized to provide a composite σ^0 equation model accounting for individual effect in regression analysis. The experimental data are compared with Small Perturbation Method. It is observed that the X-band gives better agreement up to incidence angle 50゜ for HH-polarization and 60゜ for VV-polarization as compared to the C-band. The lower angles of incidence give better results than the higher angles for observing m_g at the X-band. The multiple and partial regression analyses have also carried out for predicting the dependence of scattering coefficient(σ^0)on m_g and h_\u003crms\u003e more accurately. The analyses suggest that the dependence of dielectric constant(i.e., m_g)is much more significant in comparison to surface roughness at lower angles of incidence for both like polarizations. The results propose the suitable angle of incidence for observing bare surface roughness and soil moisture at the X-band. All these data can be used as a reference for satellite or spaceborne sensors.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright(C)2000 IEICE"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_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_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168516", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Singh, Dharmendra"}], "nameIdentifiers": [{"nameIdentifier": "5750", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamaguchi, Yoshio"}], "nameIdentifiers": [{"nameIdentifier": "19", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamada, Hiroyoshi"}], "nameIdentifiers": [{"nameIdentifier": "50", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Singh, Keshev Prasad"}], "nameIdentifiers": [{"nameIdentifier": "5753", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110003218835.pdf", "filesize": [{"value": "781.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 781900.0, "url": {"label": "110003218835.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1823/files/110003218835.pdf"}, "version_id": "674edf13-a609-4ca8-8bf8-3c301a0c2d61"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "remote sensing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "soil moisture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "surface roughness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "scattering coefficient", "subitem_subject_scheme": "Other"}, {"subitem_subject": "scatterometer", "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": "Response of Microwave on Bare Soil Moisture and Surface Roughness by X-Band Scatterometer (Special Issue on Advances in Radar Systems)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Response of Microwave on Bare Soil Moisture and Surface Roughness by X-Band Scatterometer (Special Issue on Advances in Radar Systems)"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/21339", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-02-19"}, "publish_date": "2013-02-19", "publish_status": "0", "recid": "1823", "relation": {}, "relation_version_is_last": true, "title": ["Response of Microwave on Bare Soil Moisture and Surface Roughness by X-Band Scatterometer (Special Issue on Advances in Radar Systems)"], "weko_shared_id": 2}
