Teaching and exams spring 2022

In light of the most recent infection control regulations, we will at the start of the spring semester 2022 increase our online teaching, while we at the same time try to maintain in-person teaching where this is possible. We hope to go back to more in-person teaching later on in the semester. You will be informed about any changes in teaching or examinations on the semester page, in Canvas or through your regular channels.

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.

Admission to the course

Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.

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 – Ultrasound Imaging

Overlapping courses


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.


Oral exam (or written if the number of students 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: IN9450 – Array Signal Processing

Examination support material

Language of examination

You may write your examination paper in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester. Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
