We present the basics of time reversal (TR) Acoustic Emission (AE) principle and point out the advantages of AE nondestructive testing for localization and classification of acoustic sources. This approach provides the tool for the defect localization by means of the reversal wave focusing in nonlinearity position in the material under consideration. Also, using TR operator to AE signal, we obtain convolutional signal in the closest neighborhood of acoustic source, which gives us the pure image of the real characteristics of AE source after deconvolution process applied to the signals detected.
