Head Kivva F.V., Registration Date 16-07-2001 Organization Institute of Radiophysics and Electronics NASU popup.description2 Using the method of numerical modelling the theoretical analysis of the effects of sound linear and nonlinear scattering in gas saturated layers of water whole width is conducted; the processes of metane bubbles coming to the surface, its gas exchanging with a media and condition of acoustic resonance in "flames" are studied. The dependence of echo signals spectral characteristics from oil products film presence is obtained; the influence of radiated fields wavelength, incidence angle, wind direction and velocity, radiation polarization on this characteristics is estimated.
