Sammanfattning

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.
