That error is Doppler shift.


In a word, no.

How about a few more of them, then? :-)

The Doppler effect occurs downstream of transmitting
wavefront. In fact, you've shown very clearly that no
Doppler effect occurs close enough to the transmitter
for the wave to still be a plane.

Or, to say it in your newer and better way, close
enough to the transmitter that there are no frequency
dependent errors in the path to the receiver.
