We consider the problem of developing three-dimensional (3D) spatial representations of objects by processing sparse, wide-angle radar measurements of that object. We propose an approach in which multiple interferometric SAR (IFSAR) image pairs are obtained, each using a modest angular aperture. Each IFSAR image pair is used to extract 3D scattering locations and attributes, and these points are noncoherently combined to form object reconstructions. Volume rendering methods are employed to represent these spatial points and their attributes. Reconstruction results are presented using synthetically-generated, wide-angle scattering data of a backhoe.
