What is the sound of a car engine? Well, actually, that depends very much on where you are! If you sit inside the car, and have time to listen to the engine, you’ll hear a constant humming of the machine. Quite a muffled sound, actually, because nowadays car manufacturers try to make sure that you hear as little of the engine sound as possible.

Resolution of overlapping Doppler shifted echoes
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002This paper considers the problem of estimating the time delays and Doppler shifts of a known waveform received via several distinct paths by an array of antennas. The general maximum likelihood estimator is presented, and is shown to require a 2d-dimensional non-linear minimization, where d is the number of received signal reflections.

The Doppler shift lifetimes facility
Hyperfine Interactions, 2013The Doppler Shift Lifetimes chamber is an experimental facility designed to measure the mean lifetimes of excited nuclear states that decay within femtoseconds via the detection of their Doppler-shifted γ ray transitions.

Einstein Shift and Doppler Shift
Nature, 1925MAY I ask whether the Einstein shift of spectral lines is supposed to be due to some change of frequency associated with an atomic occurrence while generating waves, or to direct influence of the gravitational potential on ether vibrations after they are generated.

Relativistic Doppler-shift effects
Physical Review D, 1985The lack of knowledge of relativistic distribution functions for interacting particles introduces uncertainty into the cosmological interpretation of Doppler shifts, particularly for systems such as quasars. Here we define an average Doppler shift, reducible to the nonrelativistic form in the appropriate limit.
