The small-angle modification of the method of spherical harmonics is generalized for the case of a point unidirectional (PU) light source in an infinite anisotropically scattering medium. Within the framework of this generalization, the vector radiative transfer equation is solved for an unpolarized PU source. Equations describing the state of polarization of the scattered radiation are reduced to the form convenient for use in engineering practice. The equations obtained are analyzed, and it is shown that the minimum of polarization coincides with the direction of sighting at the maximum of radiance, that corresponds to the Umov law.
