1. Change Detection Using Multitemporal SAR Images
Sammanfattning : Multitemporal SAR images have been used successfully for the detection of different types of environmental changes. The detection of urban change using SAR images is complicated due to the special characteristics of SAR images—for example, the existence of speckle and the complex mixture of the urban environment.

3. Urban Area Information Extraction From Polarimetric SAR Data
Sammanfattning : Polarimetric Synthetic Aperture Radar (PolSAR) has been used for various remote sensing applications since more information could be obtained in multiple polarizations. The overall objective of this thesis is to investigate urban area information extraction from PolSAR data with the following specific objectives: (1) to exploit polarimetric scattering model-based decomposition methods for urban areas, (2) to investigate effective methods for man-made target detection, (3) to develop edge detection and superpixel generation methods, and (4) to investigate urban area classification and segmentation.

4. Sea Surface Current Measurements Using Along-Track Interferometric SAR
Sammanfattning : Ocean currents affect the weather, the climate and the marine ecosystem. Observing ocean currents is important for understanding the upper-ocean layer dynamics and its interaction with the other components of the climate system. In-situ measurements are sparse and their deployment and maintenance is costly. LÄS MER
5. Sea Ice and Ocean Environmental Applications of Spaceborn SAR
Sammanfattning : The worldwide focus on our changing environment has led to an increased need to observe and characterise a range of environmental phenomena. The Arctic Ocean is particularly sensitive to climate variations. LÄS MER
