Title of the thesis:Monitoring Landscape Changes Using Satellite Radar Imagery
The general aim of this master's thesis is to test the application of satellite radar imagery on detection of landscape elements and their changes in time. The experiment was conducted in the vicinity of Bratislava, the capital city of Slovak Republic. Radar imagery was provided by the TerraSAR-X mission and by the new European Space Agency initiative, the Sentinel-1 mission. All radar images are inherently degraded by granular noise known as speckle and before application the very first step is to reduce the amount of this effect. For this purpose several speckle reduction filters were quantitatively compared and evaluated on real radar imageries. After speckle reduction, it was possible to perform object detection. The obtained results were compared with in situ measurements using global navigation satellite systems. The results have been presented by filtered images, statistical tables and diagrams.
Key words:
Synthetic Aperture Radar, spatial filtering, edge detection, TerraSAR-X, speckle noise reduction, Sentinel-1
