Abstract :
In this work we consider scattering of electromagnetic waves on the axially symmetrical spraying turbulent jets of liquids, gases and plasma. The multiple scattering of electromagnetic waves on the strong fluctuation dielectric penetration of the jet of plasma is discussed. The analytic expressions and numerical results for radar cross section and frequency spectrum scattering signal on the external surface of a turbulent jet has been found. The results are presented of numerical modeling of multiple scattering of waves on the internal surface of turbulent bodies of revolution; cone and paraboloid.
