FIELD: measuring technology.
SUBSTANCE: invention relates to measuring technology and can be used in systems that synchronize delayed copies of a nondeterministic pseudorandom signal. To do this, a coherent synchronization is used, based on the principle of frequency matching of durations and phases of intervals of spectral envelopes of interference minima (IM) created in the control spectra of the input total signals. Signals presented using the fast Fourier transform (FFT) in spectral form are subjected to interference-phase estimation of time delay parameters. Interference-spectral estimation of signal parameters is intended for determining the values of time delay, phase shift and their initial installation in the synchronization scheme.
EFFECT: increase the noise immunity of synchronization in conditions of rapid changes in the parameters of nondeterministic signals.
