Abstract : Light scattering is the basic physical limitation in certain naval operations. These include: Optical detection of submarines; Blue-green communications to submarines; and Undersea visibility in search, rescue, and mapping. To evaluate these limitations, the Navy needs solutions to the mathematical problem of multiple scattering, or radiative transfer as physicists prefer to call it. To describe this problem, we need to make a distinction between inherent and apparent properties of the seawater. The inherent properties refer to the water and the particles suspended therein: (a) the beam attenuation coefficient; (b) the volume scattering function; (c) the absorption coefficient; (d) moments of delta (spherical harmonics); (e) total scattering coefficient; and (f) alpha - S sub n. Sections I and II describe contributions to the direct and inverse problems of radiative transfer, and Sec. III lists the papers and reports prepared and published under the subject contract.
