Abstract
Expression for dispersion of measurement of the time delay from the relation signal/noise received in the conditions of prior uncertainty of rather frequency mismatch of signals on the basis of computation of cross-correlation function of the modified complex envelopes is given. The correctness of the received analytical dependence of dispersion of measurement of a time delay is confirmed with results of simulation modeling. Comparing of a mean squared deviation of the estimates of a time delay received by an optimum method and the developed method of computing and effective estimation on the basis of computation of cross-correlation function of the modified complex envelopes is carried out.
