In the article possibility of account of phase fluctuations of signals reflected is examined from littlepitch aims location in a troposphere waveguide outside distance of line-of-sight, during optimization of process of measuring of time of delay of signal. The process of optimization of measuring of distance to the aim on conditions of superrefraction is examined in supposition, that fluctuations of the signals reflected from лоцируемых aims up-diffused on a normal law, and the cross-correlation function of these fluctuations has an arbitrary kind. Within the limits of suppositions got correlation for the optimal estimation of time of delay of the reflected signals.
Keywords: phase fluctuations, cross-correlation function, dispersion
