IN5450 – Array Signal Processing
The topic is spatial signal processing with emphasis on imaging systems and direction of arrival estimation. The course put emphasis on the difference between spatial and time domain signal processing. It provides an in-depth review of classical and adaptive array processing techniques in time and Fourier domain and give an overview of their use in different application areas.
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.
- Adaptive beamforming: Optimization of beampattern, eigenanalysis methods, and how to assess the algorithms performance.
- Applications: Examples will be given from acoustic imaging, synthetic aperture sonar/radar, and tomography among others.
