Marine Vibrators And The Doppler Effect
Offshore Technology Conference, 1988ABSTRACT Marine seismic data acquired with a moving vibrator suffer phase dispersion caused by Doppler shifting of the source sweep function. The dispersion, which can be as large as several hundred degrees, is a function of frequency, ship speed, sweep type, and the time dips of reflection events.

The problem of a massive particle moving along a stretched string and subjected to a time-varying force perpendicular to the string is treated by the method of characteristics. If the force varies harmonically explicit expressions may be obtained; these are displayed.

The Doppler effect is discussed for flexure waves in beam and plate, three body waves (P, SV, SH) in an infinite solid, modal SH waves in a thick plate and a Rayleigh wave on the surface of a semi-infinite solid. The exact closed form solution for each elasto-dynamic problem is obtained and the simple equation for the Doppler frequency shift is derived

Doppler effect in aeroacoustics [PDF]
The Journal of the Acoustical Society of America, 2008 Doppler effect in aeroacoustics The prediction of acoustic fallout caused at the ground level by aircraft in flight or by launchers at take-off sets the problem of the distortion of the emitted sound spectrum by the Doppler effect. Former studies applied to this problem use a geometrical formalism based on simplifying hypotheses such as homogeneous ...

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.
