| Abstract: |
The majority of the articles in this volume celebrate the success of the
DRAO ST and its use over past 15 years as the primary instrument for the
Canadian Galactic Plane Survey (CGPS, Taylor et al. 2003). However, imagine how
much more successful the DRAO ST and the CGPS might have been if the
telescope could have observed the sky at a rate 25 to 30 times faster!
This is the promise of focal plane array systems for aperture synthesis
telescopes. Here we discuss some of the properties of one type of focal plane
array, the phased array feed system, and how it might be used in a future
radio telescope such as the Square Kilometre Array (SKA). |
