Abstract

A model for calculating the spectral radiation difference (contrast) between an object and a sea background has been developed at the Norwegian Defence Research Establishment (NDRE). The model calculates both the emitted radiance from the sea surface and the reflected sky radiance. Inclusion of a rough sea surface is also possible. The contrast has been calculated for different meteorological situations ranging from a cold, clear winter atmosphere to an overcast tropical. A comparison between the contrast in the midwave (3 - 5 micrometers ) and the longwave (7 - 14 micrometers ) band has been made.
