Abstract
The algorithm of cross-correlation function (CCF) evaluation, by means of a reverse Fourier transformation above the mutual spectrum of signals, is widely known. The evaluation of mutual spectrum is carried out as a result of execution of Fourier transformations above the input signals and subsequent complex multiplication of Fourier- transformations results. The evaluation of a mutual spectrum in acoustooptics at usage of two Bragg-cells is impeded. For CCd evaluation on sectional algorithm the combination of acousto-electronic chirp-transformations of input signal with subsequent acoustooptical multiplication of signal spectrums and the execution of a reverse Fourier-transform is expedient.
