Abstract:
The numerical examination of spectra of stellar scintillations observed through the Earth's atmosphere from space is carried out. Three models of 3D spectra of inhomogeneities forming scintillations are considered: isotropic, anisotropic, and inhomogeneities with a variable anisotropy. 2D and 1D scintillation spectra were calculated for a phase screen model in the approximation of week scintillations. It is shown, that 1D spectra for different models can be close to each other. The taking into account of a variable anisotropy does not change considerably the character of spectra in comparison with model of inhomogeneities with constant anisotropy.
