这篇文章集中于考察坚持的 scatterer interferometry (希腊语的第二十三个字母) 的技术,它经常被用来监视地球表面的变丑。在希腊语的第二十三个字母的实现的三关键步被介绍,即,(1 ) 坚持的 scatterer (PS ) 的察觉,(2 ) PS 网络的建设,并且(3 ) 希腊语的第二十三个字母建模和答案。最后, PSI 技术上的主要问题和眼界被讨论并且给。
This article focuses on reviewing the technologies of persistent scatterer interferometry (PSI), which has been often used to monitor the deformation of Earth surface. Three critical steps in the implementation of PSI were introduced, i.e., (1) detection of persistent scatterer (PS), (2) construction of PS network, and (3) PSI modeling and solution. Finally, the main problems and outlooks on the PSI technique are discussed and given.
