Results of TerraSAR-X INSAR observations in spring 2008 of land cover displacements because of karsts processes and landslides at 2 test sites in European part of Russia, which are dangerous for industrial infrastructure, are presented. The solution of temporal decorrelation problem for X-band SAR in a form of artificial and natural stable point targets is discussed. Various approaches in the estimation of the displacements depending on scene content and description as well as level of temporal decorrelation are proposed. A millimeter accuracy of TerraSAR-X measurements of land displacements using stable targets is confirmed.
