In this paper synthetic aperture radar is analyzed from an inverse scattering
perspective. It is shown that the classical point scattering model can be
generalized to a dipole scattering model. The dipole scattering model reduces
to the point scattering model for small aperture angles. For large aperture
angles or multiple illumination apertures the dipole model gives an anisotropic
reflectivity such that orthogonal scattering processes are separated. Moreover,
it is shown that both the point and dipole scattering models can be interpreted
as an initial step of a least-squares inverse scattering algorithm.
