Paper Abstract

This paper investigates the impact of considering vertically-varying turbulence and aerosol extinction on imaging of long range surface targets, compared with assuming invariant properties in the marine surface layer. Models of turbulence and aerosol extinction in the marine surface layer are presented and calculations of aerosol transmittance and of turbulenceinduced blurring and scintillation are performed and discussed under thermally unstable and stable conditions, taking into account air refraction and the Earth curvature.
