1. Change Detection Using Multitemporal SAR Images
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : 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.

2. Urban Area Information Extraction From Polarimetric SAR Data
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : 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.

3. Sea Surface Current Measurements Using Along-Track Interferometric SAR
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : 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. READ MORE

4. Urban Change Detection Using Multitemporal SAR Images
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.

5. Design of Ultra-Low-Power Analog-to-Digital Converters
University dissertation from Linköping : Linköping University Electronic PressAbstract : Power consumption is one of the main design constraints in today’s integrated circuits. For systems powered by small non-rechargeable batteries over their entire lifetime, such as medical implant devices, ultra-low power consumption is paramount. READ MORE
