摘要

The influences of atmospheric turbulence on image resolution of space-borne optical remote sensing system are discussed. The coherence length of wavefront r_0 and the variance of angle-of-arrival fluctuation σ_α~2 of sensing system are the main basis to evaluate the atmospheric influence on image resolution. In this paper, different atmospheric turbulence models are chose to calculate r_0 and σ_α~2 in order to analyze the influence of atmospheric turbulence, and the results show that the influence of atmospheric turbulence should be weak and in most cases could be ignored for for space-borne optical sensing system.
