Abstract
Currently, the most widely used distribution of slopes of the sea surface is Gram–Charlier distribution. Limitations of its use in the simulation of light reflection from the sea surface are analyzed. It is shown that Gram–Charlier distribution does not allow one to build optical image throughout the full sensing range of angles for low Earth orbit spacecraft optical scanners. Empirical relations between statistical moments of sea surface slopes and their angles are obtained.
