Paper Abstract

Different statistical properties of laser illumination through atmospheric turbulence have already been derived either in the small or strong perturbation regimes. However, modeling the instantaneous illumination remains useful for the estimation of optical system performances. using an end-to-end propagation model based on a split step algorithm leads up to heavy calculations. We propose a simplified model to provide instantaneous laser illuminations according to the C2/n profile. This simplified method has been implemented. Hypothesis taken into account and cross check with a numerical end-to-end model developed at Onera are presented.
