Abstract

Polar backscattering from a fiber-reinforced composite which contains regions of porosity, has been investigated in a number of papers [1]–[7]. Several scattering mechanisms appear to contribute to the backscattered signal. Roughly speaking the components of the backscattered signal can be attributed to effects of finite beam width, to the structuring of the material and to the existence of porosity.
