APPLICATION OF STATISTICAL RADIOPHYSICS MODELS TO IMPROVE THE RELIABILITY OF THE RESULTS OF ACOUSTIC-EMISSION TESTING AND DIAGNOSTICS OF THE PREFRACTURE STATE

Aspects of improving the reliability of the results of the acoustic em ission (AE) method on the basis of the experimentally observed statist ical distributions of AE amplitudes and time intervals are investigate d. A parameter characterizing the degree of distortion and overlap of AE pulses is introduced. Estimates of the parameter are obtained from recorded AE signals. Relations for improving the reliability of the re sults of the AE method by reconstructing the stream of AE events from recorded signals for different types of dead time and various methods for the measurement of AE pulses are derived on the basis of the model of a Poisson stream of events.
