Abstract:
Theoretical assessments of the dependence of interferometric direction device range on laser beam parameters, device geometry, and atmospheric turbulence characteristics are presented in this work. The assessments are calculated for three values of interference contrast (0.1, 0.3, and 0.5), structure parameter of turbulent atmosphere permittivity fluctuations within the 10--16 … 10-13 m-2/3 range, distances between the radiating apertures centers, equal to 1, 2, 3, 4, and 5 cm, and three radiation wavelengths (0.51, 0.63, and 1.06 µm). It is shown that the range of interferometric direction device exceeds 5 km at average turbulence intensities corresponding to most realizable in the marine and coastal atmosphere in midlatitudes and low interference contrast, equal to 0.1.
