Comparison of atmospheric correction methods in InSAR application

SONG Xiao-gang ①,LI De-ren ①②,LIAO Ming-sheng ②,WANG Shang ③(①School of Remote Sensing and Information Engineering,Wuhan University Wuhan,430079,China;② LIESMARS,Wuhan University,Wuhan 430079,China;③China Institute of Geotechnical Investigation and Surveying,Beijing 100007,China)  
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.
