Abstract

Synthetic Aperture Radar (SAR) sensors have many advantages over electro-optical sensors (EO) for target recognition applications, such as range-independent resolution and superior poor weather performance. However, the relative unavailability of SAR data to the basic research community has retarded analysis of the fundamental invariant properties of SAR sensors relative to the extensive invariant literature for EO, and in particular photographic sensors. Prior work that was reported at this conference has developed the theory of SAR invariants based on the radar scattering center concept and provided several examples of invariant configurations of SAR scatterers from measured and synthetic SAR image data. This paper will show that invariant scattering configurations can be extracted from predicted 3D data scatterer data and used to predict invariant features in measured SAR image data.
