Time-frequency Integrals and the Stationary Phase Method in Problems of Acoustic Waves Propagation from Moving Sources

Abstract

The paper is devoted to the applications of the time-frequency integrals and the two-dimensional stationary phase method for the problems of waves propagation from moving sources in acoustic dispersive media. Applying the stationary phase method we obtain the effective formula for the acoustic fields in the dispersive media generated by non-uniformly moving modulated source.
