Paper Abstract
Interferometric Synthetic Aperture Radar (InSAR) is an effective measurement of generating large scale accurate digital elevation modeling (DEM). It is an important step in InSAR processing that removes the flat earth phase. Common flattening methods work on the assumptions that the interferometric baseline does not vary by time and approximation of local flat earth. These methods do not work well in reality due to the complicated situation. This paper analyzes the model of interferometric phase. Moreover, it puts forward an advanced method which takes into account the variation of baseline related to time. Finally, the actual data test shows the feasibility and validity of the new method.
