•Large number of small antennas has
sensitivity comparable to a moderate sized antenna.
(Calibrator sensitivity ~ n * A)
•
•Wide bandwidth (Calibrator sensitivity ~ ÖBW)
•
•Even with large antennas, must rely heavily on self-calibration
to achieve dynamic range
goals.
•
•Will almost always have compact solar sources in FOV
•
•Frequency-dependence of phase variations with time can be
simply parameterized
(eg terms that scale with f and
f^-2.)
•
•Lots of time available for daily pre- and post-observation
calibration
•
•Frequency coverage suggests that communications satellites
might be useful as
secondary calibrators.
