Semi-automatic processing of InSAr data from artificial reflectors

Popis výsledku v původním jazyce

In our project, we process TerraSAR-X StripMap data in the area of Northern Bohemia, known as a large coal basin just below the slope of the Ore Mountains. Unfortunately, the area is generally decorrelated due to open mines and forest, the only correlated regions are villages, industrial areas, and some roads or railways; due to the decorrelation and the impossibility of common phase unwrapping methods, traditional InSAR cannot be used. In order to provide at least some monitoring information, we decided to install 11 artificial reflectors in the area, with distance of about 3-5 km. In the acquired TerraSAR-X scenes, the reflectors are found and the phase information, together with coordinates, is interpolated in order to be as precise as possible. Then, interferogram phases are computed for all pairs of scenes. The process of deformation evaluation is semi-automatic due to the necessity of phase unwrapping, which needs to be corrected in some cases. The processing is performed separat
