IN9450 – Array Signal Processing
Course description
Course content
The topic is spatial signal processing with emphasis on imaging systems and direction of arrival estimation. The course puts emphasis on the difference between spatial domain and time domain signal processing. It provides an in-depth review of classical and adaptive array processing techniques in the temporal and Fourier domains and gives an overview of their use in several application areas.
Learning outcome
After completing this course, you will have an understanding of:
- Apertures and arrays: Finite apertures, resolution, spatial sampling and arrays of discrete sensors, sidelobes and grating lobes.
- Beamforming: Delay-and-sum and frequency-domain beamforming, array gain and effects of finite accuracies. Coherence-based image reconstruction methods.
- Adaptive beamforming: Beampattern optimization, eigenanalysis methods, and how to assess the algorithm performance.
- Applications: Examples will be given from acoustic imaging, synthetic aperture sonar/radar, and tomography, among others. You will learn about central wave propagation and simulation concepts.
- Current research: Know how the theory explained is used in current research and have an overview of the research performed within this field at the Department.
Admission to the course
PhD candidates from the University of Oslo should apply for classes and register for examinations through?Studentweb.
If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.
PhD candidates who have been admitted to another higher education institution must?apply for a position as a visiting student?within a given deadline.
