The velocity of electromagnetic radiation in a vacuum is a constant which depends only upon the magnetic permeability and electrostatic permittivity of free space. This velocity is independent of any movement of the source or observer, but the same is not true of the wavelength and frequency of radiation.

Doppler effect, as currently formulated. uses numerical phase invariance and any linear coordinate transformations with identity transformations of nonzero spatial coordinates transverse to a rectilinear uniform relative motion; this is shown to subtly deny presumed motion, angular aberration effects, and Doppler effect.

On The Relativistic Doppler Effect
Journal of the Optical Society of America, 1939The theory of the recent experiment of Ives and Stilwell is developed on the basis of the special theory of relativity. The predictions are shown to be identical with those obtained from electron theory. A possible source of error in the experiment is pointed out, and a method for its elimination is suggested.
