I agree with your conclusions regarding the case of isotropic

I agree with your conclusions regarding the case of isotropic
atmospheric noise. This is the same reason that cold space looks like 3
Kelvin regardless of how high the antenna gain. As the antenna gain goes
up you reinforce to a greater degree a lesser slice of the overall pie.
This ends up
To assess the impact of amplifier circuit noise in "active" receive arrays,
we only need to be concerned with the contribution of amplifier circuit
noise relative to atmospheric noise. The details of how signals are phased
in any particular array do not matter. The objective is to keep the
