This whole discussion points out the fallacy of trying to understand
reflections by sending a CW signal. Consider a 100W pulse radar transmitter.
Also, assume the transmitter rurns off between pulses ( a good assumption),
and that the antenna mismatch causes 3% of the power to be reflected.

When the pulse reaches the antenna, 97W is transmitted, and 3W is returned.
All of this 3 W is reflected by the transmitter, and a second pulse is
produced where 2.91W is radiated and .09 W is reflected back. This is
re-reflected, and a third pulse is produced where .0873 W is radiated and
..0027 W is reflected, etc, etc.

Keeping everything simple and not getting into peripheral issues is

The assumption that the source is outputting (forward power
minus reflected power) is essentially saying that all amplifiers
are perfectly matched and re-reflect all reflected power.
That seems like a stretch to me.
