The article presents efficiency of increasing the accuracy of the phase difference measuring based on dependencies of the root-mean-square deviation of phase difference fluctuations on ratio of the instant amplitudes of spatially-separated low-directional antennas output signals. The results were obtained during the full-scale experiment conducted in autumn. The measurements were carried out on the surface routes of radio waves propagation in centimeter range.
