Diffraction of Impulse Sound Signals on Spheroidal Body, Put in Plane Waveguide

Abstract

With the help o f the Fourier t ransform and characteristics of the stationary (continuos) sound signal are calculated the impulses, scattered by the ideal spheroid, placed in the waveguide. In the first part of the paper is presented the method of the imag inary sources and imag inary scatterers from the solution of the problem of the sound diffraction on the spheroidal body, put in the plane waveguide. In the second part of the paper are calculated the impulse signals with different filling, scattered by the the ideal soft spheroid, placed in the plane waveguide.
