Abstract

In the article possibility of account of phase fluctuations of signals reflected is examined from littlepitch aims location, 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. Using the obtained ratios to determine the delay time and the variance of the group delay estimation, the target distance meter was synthesized under the radar of the target above the sea beyond the line of sight for the case when the correlation function of phase fluctuations is described by an exponential function. The proposed optimal estimation algorithm and rangefinder can be used to construct promising radar locations for low altitude targets. The use of such a meter can improve the accuracy of measuring the target range from 2 to 2,5 times.
