16. Spaceborne Synthetic Aperture Radar for Sea Ice Observations, Concentration and Dynamics
Abstract : Spaceborne Synthetic Aperture Radar (SAR) is the primary choice for sea ice monitoring due to its all-weather, day-and-night capability and regular delivery of high resolution images. This thesis presents methods for estimation of sea ice concentration and drift, a multi-sensor study of Baltic Sea ice radar signatures and an interferometric study of landfast sea ice. READ MORE

17. Particle filtering for positioning and tracking applications
Abstract : A Bayesian approach to positioning and tracking applications naturally leads to a recursive estimation formulation. The recently invented particle filter provides a numerical solution to the non-tractable recursive Bayesian estimation problem. As an alternative, traditional methods such as the extended Kalman filter. READ MORE

18. Exploiting Sparse Structures in Source Localization and Tracking
Abstract : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. READ MORE

19. Fast Adaptive Numerical Methods for High Frequency Waves and Interface Tracking
Abstract : The main focus of this thesis is on fast numerical methods, where adaptivity is an important mechanism to lowering the methods' complexity. The application of the methods are in the areas of wireless communication, antenna design, radar signature computation, noise prediction, medical ultrasonography, crystal growth, flame propagation, wave propagation, seismology, geometrical optics and image processing.

20. Filtering and modelling for automotive safety systems
Abstract : This thesis makes five important contributions to the development of an automotive safety system: filtering algorithms, three modelling frameworks concerning the usage of radar detections in tracking, vehicle motion, and decision-making for intervention decisions, and finally the implementation architecture.In the filtering context, we have developed a new sigma-point method for estimating the moments of a transformed Gaussian random variable.
