Abstract
Physical modeling of acoustic signal backscattering by discrete random inhomogeneities is performed. The behavior of the transverse correlation radius of the scattered field amplitude is studied. Its experimental dependences on the transducer aperture, on the angle of sounding of an inhomogeneity-containing plane, and on the correlation properties of the scatterer position on this plane are derived. Qualitative theoretical models in the framework of the theory of single scattering are proposed which provide an explanation to the phenomena observed.
