Paper Abstract

Investigation of microrelief's influence on parameters of holographic correlator of acoustic signals by mathematical modeling was carried out. The real part of correlation integral was estimated by changing amplitude and frequency of filtered signal. Including of simple function in from of M(x) equals sin(2 (pi) (tau) x) for microrelief modeling showed possibility to avoid misleading signals. Results of mathematical modeling and experimental measurements are compared.
