Abstract:

To calculate scintillation spectra one assumes that in the atmosphere the field of the fluctuations of the relative refractive index is locally isotropic on the sphere and homogeneous in height. In the phase-screen approximation scintillation spectra are expressed in terms of spectra of the refractive index fluctuations. The sphericity of the atmosphere is shown to affect the anisotropic fluctuations of the refractive index with an anisotropy coefficient of more than (a_e/H₀)^1/2. Gaussian and power spectra with an arbitrary coefficient of anisotropy are also considered.
