John,
We could not find any well-cited or commonly known circumstances in a
related field (to remote sensing) where the antenna temperature can mean
"the temperature of the antenna itself." Maybe you could suggest a case
where antenna temperature has such a meaning in terms of measurements so
we can identify a potential conflict. As far as we can tell, antenna
temperature is used to "relate the power emitted by [a] source to an
interesting physical property of that source."

But I see a potential conflict with those measurements of antenna temperature that are taken strictly to learn what the temperature of the antenna is, and having nothing to do with the power per unit bandwidth received from a source.
