Abstract

Free-space optical communications (FSOC) are very sensitive to atmospheric turbulence as they induce local variations of the refractive index and alter the propagation of light. The SHAdow BAnd Ranger (SHABAR) uses solar scintillation to estimate a profile of refractive index structure constant, which can be integrated into other turbulence metrics like Fried parameter, isoplanatic angle and coherence time.
