The method considers image pairs of the same scene acquired at different time instants. The CD method aims to maximize the probability of detection (PD) and minimize the false alarm rate (FAR). Such aim fits into a multiobjective optimization problem, since maximizing the probability of detection generally implies an increase in the number of false alarms. In that sense, varying the RPCA regularization parameter leads to PD variation with respect to FAR, which is known as receiver operating characteristic (ROC) curve. To evaluate the proposed method, the CARABAS-II data set was considered. The experimental results show that RPCA via principal component pursuit (PCP) can provide a good trade-off between PD and FAR. A comparison between the results obtained with the proposed method and a classical CD algorithm based on the likelihood ratio test provides the pros and cons of the proposed method.<\/jats:p>","DOI":"10.3390\/rs12121916","type":"journal-article","created":{"date-parts":[[2020,6,15]],"date-time":"2020-06-15T05:56:27Z","timestamp":1592200587000},"page":"1916","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Change Detection in UWB SAR Images Based on Robust Principal Component Analysis"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1405-4718","authenticated-orcid":false,"given":"Christofer","family":"Schwartz","sequence":"first","affiliation":[{"name":"Aeronautics Institute of Technology (ITA), S\u00e3o Jos\u00e9 dos Campos, SP 12228-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9267-6718","authenticated-orcid":false,"given":"Lucas P.","family":"Ramos","sequence":"additional","affiliation":[{"name":"Aeronautics Institute of Technology (ITA), S\u00e3o Jos\u00e9 dos Campos, SP 12228-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0290-0080","authenticated-orcid":false,"given":"Leonardo T.","family":"Duarte","sequence":"additional","affiliation":[{"name":"School of Applied Sciences (FCA), University of Campinas (UNICAMP), Limeira, SP 13484-350, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcelo da S.","family":"Pinho","sequence":"additional","affiliation":[{"name":"Aeronautics Institute of Technology (ITA), S\u00e3o Jos\u00e9 dos Campos, SP 12228-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6643-312X","authenticated-orcid":false,"given":"Mats I.","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Blekinge Institute of Technology (BTH), 37179 Karlskrona, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viet T.","family":"Vu","sequence":"additional","affiliation":[{"name":"Blekinge Institute of Technology (BTH), 37179 Karlskrona, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0856-5391","authenticated-orcid":false,"given":"Renato","family":"Machado","sequence":"additional","affiliation":[{"name":"Aeronautics Institute of Technology (ITA), S\u00e3o Jos\u00e9 dos Campos, SP 12228-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1016\/j.cviu.2013.11.009","article-title":"Robust PCA via principal component pursuit: A review for a comparative evaluation in video surveillance","volume":"122","author":"Bouwmans","year":"2014","journal-title":"Comput.
