| Abstract: | Several methods currently used to correct atmospheric effect in InSAR application are described firstly in this paper.Then,their advantages and disadvantage are analyzed thoroughly.At the same time,the requirements and problems when using these methods are discussed.The authors indicate that selection of the method depends on data condition,environment of area of interest and requirement of accuracy,sometimes the combination of several methods would be better.Finally,development prospect for future research and applications are presented. |
