A bispectral approach to signal processing is proposed which permits recognizing defects in engineering structures when inspecting the parameters of the surface wave field. The approach is based of using an adaptively adjustable orthonormal basis. A series of experiments demonstrating the high effectiveness of the approach is carried out.
