Abstract

Rad obuhvaća opću problematiku primjene geodetske tehnologije i tehnike poznatu kao radar. Utvrđuje se uloga umjetnih satelita sa SAR radarskom tehnologijom i njihova primjena u interferometriji odnosno mogućnost primjene proizvoda snimanja Sentinel-1 misije. Temelj istraživanja ovog rada je uočavanje deformacija uzrokovanih potresom na području Zagreba 22.3.2020. Obrađivani podaci su dobiveni snimanjem istražnog područja Sentinel-1A i B satelitima, a sama obrada je provedena pomoću SNAP-u softverskog programa koji je izrađen za tu namjenu. Obrada snimaka se provodi u SNAP softveru kroz 4 faze. Proces obrade podataka podrazumijeva korištenje SNAP operatera čija je namjena opisan te su analizirani produkti obrade. Kao rezultat konačne obrade dobivena je maska deformacija istražnog područja koja se implementira u Google Earth u svrhu utvrđivanja područja s najizraženijim deformacijama tla.

Abstract (english)

This paper covers the general issues of application of geodetic technology and techinques known as radar. The role of artificial satellites with SAR radar technologyes is being determined and their application in interferometry, i.e. the possibility of using Sentinel-1 mission product. The base line of this research is observation of deformation caused by the earthquake in area of Zagreb on March 22, 2020. The processed data of exploration area is obtained by Sentinel-1A and B satellites recordings. Processing of it was done by using a SNAP software that is special designed for that purpose. Image processing is performed in SNAP software through 4 phases. The data processing implies to the use of SNAP operators whose purpose and products are described through the paper. As a result of the final processing, a deformation mask of the exploration area is made. Mask is implemented in Google Earth with purpose of determination of expressed soil deformation in the area.
