Abstract :
Until now mostly in studying propagation and scattering phenomena the cases of isotropic casual inhomogeneous media has been considered. The necessity of analysis of real problems of signal propagation in non-stationary anisotropic casual media such as: turbulent flows of liquids, gases and plasma requires the development of new methods of analysis. In present work the propagation of waves, falling under an arbitrary corner on the turbulent flow with an inhomogeneous structure of the turbulence velocity and concentration is considered. The transformation of the frequency spectrum of an electromagnetic signal propagating through a turbulent flow is investigated.
