โœฆ Synopsis


The Doppler effect for the modulation of a wave signal is investigated. This group Doppler effect is considered for rays in inhomogeneous, dispersive, absorbkg, anisotropic and time-varying media. In addition, the receiver or scatterer is allowed to move with respect to the medium. It is shown that the new effects depend on the group velocity and its direction relative to the normal.

The swell of a moving typhoon has the same Doppler effect as a moving sound source. Both originate from the variations in an energy flux. In a sound source this is called a frequency shift. In a typhoon it is a swell wave height change. A distant typhoon may generate very high waves through the Dopp
