1. Sea Ice and Ocean Environmental Applications of Spaceborn SAR
Abstract : 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. READ MORE

2. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data
Abstract : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. READ MORE

3. Detection and classification of sea ice from spaceborne multi-frequency synthetic aperture radar imagery and radar altimetry
Abstract : The sea ice cover in the Arctic is undergoing drastic changes. Since the start of satellite observations by microwave remote sensing in the late 1970's, the maximum summer sea ice extent has been decreasing and thereby causing a generally thinner and younger sea ice cover. READ MORE

4. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery
Abstract : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.

5. Sea Ice Concentration Estimation and Ice Type Classification from Dual-Frequency Satellite Synthetic Aperture Radar
Abstract : The sea ice cover in the Arctic has undergone dramatic changes in recent years. The perennial sea ice extent is decreasing by 12.2 % per decade while annual mean sea ice thickness has decreased by more than 2 m for the central Arctic Basin from 1975 to 2012. READ MORE
