INF9410 – Space-time signal processing
Course description
Schedule, syllabus and examination date
Course content
- Description of signals in space and time: The wave equation, spatial Fourier transform and wave number, phase and group velocity, dispersion and attenuation, refraction and dispersion, spatial noise.
- 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.
- Adaptive beamforming: Optimization of beampattern, eigenanalysis methods.
- Applications: Examples will be given from ultrasound imaging and synthetic aperture radar among others.
Learning outcome
The course gives an introduction to spatial signal processing, with emphasis on the differences compared to time domain signal processing. The course will also give an understanding of basic terminology in acoustics and electromagnetics required to master theory and realization of imaging systems based on signal processing.
In addition, each PhD student will be given an extended curriculum within the field/research area of the course. The syllabus must be approved by the lecturer so that the student can be admitted to the final exam.
Admission
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.
Prerequisites
Recommended previous knowledge
INF3470 – Digital signalbehandling (continued), STK1100 – Probability and Statistical Modelling and MAT1120 – Linear Algebra.
Overlapping courses
- 9 credits overlap with IN350
- 10 credits overlap with INF5410 – Signal processing in space and time (continued)
Teaching
2 hours of lectures and 1 hour group work. There will be mandatory assignments which must be approved in order to take the exam. Note that the assignments in INF9410 will be more extensive than the ones in INF5410.
Examination
Oral exam.
Grading scale
Grades are awarded on a pass/fail scale. Read more about the grading system.
Explanations and appeals
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.
Other
The subject is regarded equal to IN350 when practicing exam regulations.
Note that the first lecture is mandatory.
