To extract damaged areas automatically, it is essential to understand the relationships among the sensor specifications, acquisition conditions, and land cover. Our previous studies developed a method for estimating the phase noise of interferograms using several pairs of TerraSAR-X series (TerraSAR-X and TanDEM-X) datasets. Atmospheric disturbance data are also necessary to interpret the interferograms; therefore, the purpose of this study is to estimate the atmospheric effects by focusing on the difference in digital elevation model (DEM) errors between repeat-pass (two interferometric SAR images acquired at different times) and single-pass (two interferometric SAR images acquired simultaneously) interferometry. Single-pass DEM errors are reduced due to the lack of temporal decorrelation and atmospheric disturbances. At a study site in the city of Tsukuba, a quantitative analysis of DEM errors at fixed ground objects shows that the atmospheric effects are estimated to contribute 75% to 80% of the total phase noise in interferograms.<\/jats:p>","DOI":"10.3390\/s18072336","type":"journal-article","created":{"date-parts":[[2018,7,19]],"date-time":"2018-07-19T03:50:43Z","timestamp":1531972243000},"page":"2336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Evaluation of Atmospheric Effects on Interferograms Using DEM Errors of Fixed Ground Points"],"prefix":"10.3390","volume":"18","author":[{"given":"Takashi","family":"Nonaka","sequence":"first","affiliation":[{"name":"College of Industrial Technology, Nihon University, Chiba 2758575, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohito","family":"Asaka","sequence":"additional","affiliation":[{"name":"College of Industrial Technology, Nihon University, Chiba 2758575, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keishi","family":"Iwashita","sequence":"additional","affiliation":[{"name":"College of Industrial Technology, Nihon University, Chiba 2758575, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"606","DOI":"10.1109\/TGRS.2009.2031062","article-title":"The TerraSAR-X mission and system design","volume":"48","author":"Werninghaus","year":"2010","journal-title":"IEEE Trans.
