%X In order to further improve the practicability of InSAR technology, it is essential to study how to estimate and eliminate the undesired impact of atmospheric effects. In this study, the causes of atmospheric path delay are elaborated and their temporal/spatial distributions in repeat-pass InSAR are analyzed. A new method is proposed to correct the atmospheric effects in high-resolution tandem-mode InSAR through the use of an existing low-resolution DEM. The resultant elevation models obtained with and without the atmospheric correction are compared with the 30m-resolution ASTER GDEM to verify the effectiveness of the proposed method in terms of topographic mapping accuracy.
