Paper Abstract

In the up-to-date optical processing of information the special attention is paid to the procession of non-stationary signals. Time-frequency distribution are widely applied for analysis of such signals lately. The possibility of using cross-Wigner's distribution (CWD) was used theoretically. The experiment verification of the possibility of the affined signal recognition by the moments method was carried out taking into account that the CWD section corresponding to ω = ω0 in case of the symmetrical envelope of the reference signal coincides with the cross-correlation function.
