20.500.12556/DKUM-59662 DETEKCIJA SPREMEMB V RADARSKIH SLIKAH SAR CHANGE DETECTION WITHIN SAR DATA V magistrskem delu je opisan princip detekcije sprememb površja Zemlje s pomočjo radarskih slik SAR, ki so bile zajete s satelitom TanDEM-X. Opisani so tudi principi delovanja radarja z umetno odprtino, načini zajema podatkov ter osnove interferometrije V prvem sklopu magistrskega dela, je bil cilj predlagati metodo za zaznavo gozdne površine v slikah SAR. V drugem delu so bile s pomočjo SAR interferometrije zaznane spremembe na kroni gozdov v okolici Postojne. Slike SAR, so bile zajete v razmaku leta oziroma dveh, zato se je v tem času spremenila postavitev satelitov v orbiti. Uporabili smo satelitske slike, ki so bile zajete z različno pravokotno oddaljenostjo med sateliti, ki vpliva na resolucijo višine. Dobljeni rezultati, prikazujejo detekcijo sprememb med leti 2012 in 2014 za območje Postojne. This master thesis describes the principle of the detection of changes of the land surface using SAR radar images, which were covered by the satellite TanDEM-X. Thesis describes the principles of operation of the radar with the artificial opening, the methods of data acquisition and the basics of the interferometry. In the first part of the master thesis, the aim was to propose the method for detection of the forest areas in the SAR images. In the second part of the thesis, the SAR interferometry was used to detect the changes on the forest crown area in the vicinity of Postojna. The SAR images were recorded between one and two years, and the placement of the satellites in the orbit had been changed during that time. The satellite's images were recorded with the different perpendicular distances between the satellites, that effects on the resolution of the height. The obtained results, show the detection of the changes between 2012 and 2014 for the area of Postojna.
