"The project goal is to use interferometric stack processing in the region affected by undermining combined with open-cast mining which is partly covered by vegetation for subsidence detection. Urban objects are built on the waste dump and these are suspected (or even known) to subside. They are usually coherent; however, their surroundings is usually not and if a discontinuity in the coherence appears, it may be a problem to perform the phase unwrapping reliably. Therefore, the postprocessing will also require a method to correct the phase unwrapping errors and thus a new method for phase unwrapping will be developed.Another part of the project is the permanent scatters (PS) processing: investigation, if there are enough permanent scatters in the processed area, and if the estimated velocity is accurate enough (though probably not constant). The data will be compared with data obtained by classical techniques (such as leveling; where available). Methods for assessment of a non-linear deformation"@en . . "2010-12-31+01:00"^^ . . . . .
