Principles and Applications of Interferometry SAR

The principles and applications of interferometry SAR and differential interferometry SAR are overviewed. Various patterns of principles of interferometry SAR, differential interferometry SAR and data processing flow are discussed by comparing the differences between InSAR and common photogrammetry and remote sensing. After briefly introducing the application fields of InSAR, much attention is paid to the applications of InSAR to terrain surveying, volcanic terrain surveying and D InSAR to monitoring ground subsiding. The existing problems and application envisions are also presented in the last part of this paper.
