ACOUSTIC FIELD OF A SOURCE MOVING ALONG THE SURFACE OF A LAYERED WAVE-GUIDE

The problem of determining the far acoustic field of a source moving nonuniformly along the surface of a layered waveguide is investigated. The method of investigation permits the long-time, long-range asymptotic behavior of the field of a moving source to be determined from the asymptotic behavior of the Green's function of the steady-state problem. The resulting asymptotic formulas are uniform in the neighborhoods of critical frequencies.
