Abstract
  • The modulation transfer function (MTF) of a simple submarine viewing situation is computed as a function of range and sea-water properties. For the cases considered, we found that the MTF follows the simple exponential law, exp(-ω/ω₀), where ω is the spatial frequency in lines/deg and where ω₀ is a complicated function of the range, scattering albedo, and shape of the scattering phase function. A set of graphs summarizes the dependence of ω₀ on the inherent optical properties c and a β(γ).
