N2 - Polarimetric signatures can be used to sup- port target identification in the context of Synthetic Aperture Radar (SAR). We derive analytic models for Huynen's polarimetric signatures within the SAR image domain for classes of localized scatters which are commonly found in a composite targets. Specifically, we consider convex surfaces, curved and straight edges, and dihedrals. We use asymptotic techniques to construct the multi-frequency multi-aspect-angle scat- tered fields, then apply the SAR imaging analytically to calculate the polarimetric images near the corre- sponding hot spot regions, and finally extract the local polarimetric features and consider the identification of the relevant sub-scatterers. The polarimetric signa- tures of the sub-scatterers within the SAR image do- main, in rather large areas near the corresponding hot spots, are shown to be essentially the same as the con- ventional polarimetric signatures of each sub-scatterer in isolation.
