Is that a frequency shift or a phase shift? The transmitter is moving at the same speed as the receiver. That motion changes the transit time between the pair, but if the velocity is constant, that makes a time/phase offset rather than a frequency offset. Do get a frequency offset you want a Doppler where one end is moving relative to the other. -- These are my opinions, not necessarily my employer's.
