Composite materials with carbon reinforced fibres now are widely applied in aircraft and space techniques. The influence of roughness to sensor signal is amplified and becomes comparable and in some cases more amplitude of a modulation pulse of a surface defect. Statistical and probability researches spectral and wavelet methods of identification have been done. Methods have been tested on more than two millions copies of signals of surface cracks.
