Discussion of elastic wave backscatter from an inhomogeneous layered part of a composite is made with the computational results by using a special layer elements. The stacking of linear inhomogeneous layer element, say LILE, has been certified as an excellent model for the computation of a gradient inhomogeneous layer. Intensity curves of the backscatter calculated as a function of incident wave number are presented in a wide frequency range, and characteristic relations between the inhomogeneous structure and the backscatter intensity are discussed. The results show that some peaks appear on the curves. Study of the characteristic features provides us viable clues for computation to get the information on layering structure and spatial exponential decay of inhomogeneous material constants of composites.
