IN9450 – Array Signal Processing

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.

IN3190 – Digital Signal Processing/IN4190 – Digital Signal Processing, MAT1120 – Linear Algebra, IN1910 – Programming with Scientific Applications/IN1010 – Object-oriented Programming and IN3015 – Ultrasound Imaging/IN4015

Teaching

4 hours of tuition per week that will be a mix of lectures and plenary review of exercises, etc.

The mandatory assignments must be approved prior to the exam. Approval of a mandatory assignment is only valid for the same year as the assignment is submitted.?Rules for mandatory assignments.?Note that the assignments in IN9450 will be more extensive than the ones in IN5450.

You should familiarize yourself with the rules that apply to?the use of sources and citations. If you violate the rules, you may be suspected of?cheating/attempted cheating.

Examination

Oral exam (or written if the student number is high).

It will also be counted as one of?your three?attempts to sit the exam for this course, if you sit the exam for one of the following courses: IN5450 – Array Signal Processing
