Polar backscattering from an immersed specimen of a fiber-reinforced composite consists of several components, due to quite different scattering mechanisms. These include backscattering from the water-specimen interface, from internal irregularities of the fiber-matrix structuring and from single flaws or flaw distributions. In this paper, these backscattering mechanisms are modeled and the results of backscattering calculations for a composite containing regions of porosity are worked out and compared with experimental data.
