    Experimental studies of acoustic backscattering in the Rayleigh region (0.1 ≤ ka ≤ 1.0) from fiber-reinforced composites were conducted. A significant increase in backscattering was observed for those orientations which place the axis of the fibers or other discontinuities at normal incidence to the acoustic beam. Fiber orientations and the distribution of cracks within specific plies were easily mapped by this technique.
