Influence of the sizes statistics distribution of bottom discrete inhomogeneous on backscattering of acoustic waves

The influence of the distribution of discrete inhomogeneities in size on the average intensity of backscattered acoustic signals is investigated. It is shown that the appearance of scatterers of different sizes on the "translucent" bottom leads to an increase in the average backscattering intensity in comparison with scattering by inhomogeneities of the same size. It is proved, that in the case of a reflecting bottom the contribution of the interference term to the average intensity of backscattering on inhomogeneities of different sizes decreases with increasing mean size of the scatterers.
