The conventional supervirtual refraction interferometry (SVI) method can improve the SNR of first arrivals to a certain extent; however, it is not suitable for seismic data that interfered by strong noise. In order to better process the first arrivals at far offsets with serious noise interference, we propose a modified method, in which SVI implemented in the Radon domain (RDSVI) due to the cross-correlation in the Radon domain have a better effect. According to the kinematic characteristics of first arrival refractions, SVI is performed in the linear Radon domain. Both synthetic data and field data demonstrate the proposed method can enhance the effective signal and attenuate the strong noise simultaneously, so as to significantly improve the SNR of the first arrival data. Meanwhile, the RDSVI method is tested on the first arrival data with missing traces, which proves that this method can overcome the influence of abnormal traces and is suitable for the reconstruction of sparsely sampled seismic data.<\/jats:p>","DOI":"10.3390\/rs15020384","type":"journal-article","created":{"date-parts":[[2023,1,9]],"date-time":"2023-01-09T04:47:08Z","timestamp":1673239628000},"page":"384","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Supervirtual Refraction Interferometry in the Radon Domain"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9116-7129","authenticated-orcid":false,"given":"Yizhe","family":"Su","sequence":"first","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, Jilin University, Changchun 130026, China"},{"name":"College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"given":"Deli","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, Jilin University, Changchun 130026, China"},{"name":"College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"given":"Bin","family":"Hu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, Jilin University, Changchun 130026, China"},{"name":"College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"given":"Xiangbo","family":"Gong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, Jilin University, Changchun 130026, China"},{"name":"College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4576-4560","authenticated-orcid":false,"given":"Junming","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, Jilin University, Changchun 130026, China"},{"name":"College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"903","DOI":"10.1190\/1.1441970","article-title":"Tomographic determination of velocity and depth in laterally varying media","volume":"50","author":"Bishop","year":"1985","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1190\/1.1436864","article-title":"Tomostatics: Turning-ray tomography + static corrections","volume":"11","author":"Zhu","year":"1992","journal-title":"Lead.
