Polarization correction to Kennaugh´s target impulse response formulation and its application to the interpretation of Huynen´s Mueller matrix parameters in radar polarimetry

Based on Bennett´s time-domain first order correction to the Physical Optics current approximation, a relationship between the linear monostatic scattering matrix elements and the specular point geometry (electrical principal curvatures) of a radar scatterer is established. The resulting relations are then applied to Huynen´s Mueller matrix parameters derived from Kennaugh´s radar target polarization characteristic operator theory.
