Abstract
The influence of the atmospheric inhomogeneities on the directivity of the linear self-focusing antenna array (SFAA) is considered when describing the atmosphere with the theory of the local-isotropic turbulent medium. Two cases are analyzed when a size of the SFAA subaperture is smaller or larger than the external scale of the medium turbulence. It is shown that results of the mean directivity estimation for the two cases are well agreed qualitatively with the analogous estimates obtained when describing the atmosphere with the help of the Gaussian correlation function of its refractive index fluctuations.
