2-PASS DIFFERENTIAL INTERFEROMETRY IN THE AREA OF THE SLATINICE ABOVE-LEVEL DUMP
Original language description
We concentrate on areas with abandoned open brown coal mines, or undermined areas. We made analyzes of terrain deformation in the area of the Slatinice above-level dump that is monitored because of potential terrain deformations. The 2-pass differentialinterferometry method was used. Interferometric processing was performed in the GAMMA software. The differential interferogram for the 2-pass method was filtered and then unwrapped. Due to filtering we achieved much better coherence. Unwrapped phase of that differential interferogram can be used for a terrain-deformation detection more profitably. An important feature of this method is that all measurements are relative. Theoretically, the phase of the differential interferogram should be zero in the areas of no deformation, but there are systematic errors influencing the measurements and therefore the deformations can be determined only relatively with respect to the vicinity. Expected deformations can be described quantitatively. For
