Multi-Dimensional Filtering

Last updated 4253 days ago by Russ Taylor

Multi-dimenisional signal processing groups at the University of Calgary and the University of Victoria are collaborating on development of efficient 3D space-time filtering techniques that operate on focal plane phased array and dense aperture array signals in order to improve the signal to noise ratio and form optimal beams.

The figure below shows the space-time distribution of the signals from the forward beam (or signal of interest -SOI), and of signals from over-the-horizon radio frequency interference (RFI) and from mutual coupling of the phase array antenna elements (MC).

By designing fast and efficient 3-dimensional space time filter systems that operate on the data streams from the millions of SKA receiver systems, real-time beam forming can be implemented that, at the same time, reduce the effects of unwanted signals.
