ASKAP is designed to be a high speed survey instrument with high dynamic range. This requires an extremely wide field-of-view interferometer with Phased Array Feeds (PAFs). The PAF has a total of 188 elements, 94 in each of two polarizations.

The specification for ASKAP is:

  • A total collecting area of approximately 4,000 square metres, from 36 antennas each 12 metres in diameter
  • System temperature less than 50 K
  • Frequency range from 700 MHz to 1.8 GHz
  • 300 MHz instantaneous bandwidth
  • 36 independent beams, each of about 1 square degree, yield overlapping to a 30 square degree field-of-view at 1.4 GHz
  • Maximum baseline of approximately 6 km
  • Full cross-correlation of all antennas
  • Possible remote array station capability located in NSW, approximately 3,000 km from the core site.
