Three-Dimensional Target Visualization from Wide-Angle IFSAR Data

This paper considers the problem of developing three-dimensional (3-D) spatial representations of objects by processing wide-angle radar measurements of that object. It proposes an approach in which a sparse sampling of data is obtained such that multiple interferometric synthetic aperture radar (IFSAR) image pairs are obtained, each using a modest angular aperture. Each IFSAR image pair is used to extract 3-D 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 wideangle scattering data of a backhoe.
