Formulae are developed for the Doppler shift at signals that either go directly from the emitter E to the missile M or that reach the receiver R after they have been reflected from M, E, M, and R may have any velocity relative to the heterogeneous atmosphere. The derivation of the formulae accounts for the influence of the time needed for the frequency measurement on the Doppler shift. As a consequence, the refractive index, the velocities or velocity components that enter the formulae, are mean values over well defined intervals in space or time. The relation between the error in the velocity measurement and the time measurement is established.
