description	Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR™) is a remote sensing technique based on Differential InSAR (DInSAR) approaches. PSInSAR™ makes it possible to identify pixels that present stabilized phase related to the dispersion index. These pixels contain dispersed permanent features as man-made structures which includes bridges, dams, the building roofs, buildings, houses, and some natural features such as rocks and quarries. Thus, by analyzing the phase of these pixels, PSInSAR™ can overcome some difficulties found in the DInSAR technique such as problems related to atmospheric, temporal, and spatial decorrelations. Since its inception in the early 2000s and due to its ability to map surface deformation with millimeter precision, PSInSAR™ has been widely used to recognize deformation in risk areas such as sink/uplift and landslides. Thus, this article sought to describe the basic principle of the PSInSAR™ technique, focusing on how it has been used in the national and international context. In addition, we also show some commercial and open-source packages for PSInSAR™ processing.

A PSInSAR™ usa pixels que contenham dispersores persistentes que são caracterizados por obras de engenharia como pontes, taludes, telhados, casas, prédios, e algumas feições naturais como rochas. Por meio da análise da fase desses pixels, a PSInSAR™ consegue superar algumas dificuldades encontradas com a DInSAR, tais como, problemas correlacionados com a falta de correlação atmosférica, temporal e espacial. Desde a sua idealização no início dos anos de 2000 e devido a sua capacidade de mapear deslocamentos superficiais a uma acurácia milimétrica, a PSInSAR™ vem sendo amplamente usada em estudos sobre subsidências, deslizamentos, monitoramento de barragens, monitoramento de minas e de estruturas de engenharia no modo geral. Nesse sentido, o presente artigo descreve o princípio básico de funcionamento da técnica, investiga a sua aplicabilidade no âmbito nacional e internacional e apresenta os pacotes de processamento existentes no mercado assim como o acesso de dados interferométricos que possibilitam à utilização da PSInSAR™.Universidade Federal de Uberlândia2023-03-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/6610210.14393/rbcv75n0a-66102Brazilian Journal of Cartography; Vol. 75 (2023): Continuous PublicationRevista Brasileira de Cartografia; v. 75 (2023): Publicação Contínua1808-09360560-4613reponame:Revista brasileira de cartografia - RBC (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/revistabrasileiracartografia/article/view/66102/35720Copyright (c) 2023 Sérgio da Conceição Alves, Cláudia Pereira Krueger, Regiane Dalazoanahttps://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccessAlves, Sérgio da ConceiçãoKrueger, Cláudia PereiraDalazoana, Regiane Alves, Sérgio da ConceiçãoKrueger, Cláudia PereiraDalazoana, Regiane2024-04-22T16:32:04Zoai:ojs.www.seer.ufu.br:article/66102Revistahttps://seer.ufu.br/index.php/revistabrasileiracartografia/indexPUBhttps://seer.ufu.br/index.php/revistabrasileiracartografia/oairevbrcartografia@gmail.com1808-09360560-4613opendoar:2024-04-22T16:32:04Revista brasileira de cartografia - RBC (Online) - Universidade Federal de Uberlândia (UFU)false
