Electromagnetic backscatter predictions using XPATCH

The ability to accurately identify objects solely from their electromagnetic backscatter is of continuing interest. In order for object identification to be practical, a comprehensive catalog of signatures must be generated. The prediction code XPATCH is one tool capable of generating such a catalog. It is a high frequency polarimetric code based on the shooting and bouncing ray (SBR) method, physical optics (PO), and the incremental length diffraction coefficient (ILDC) formulation. XPATCH utilizes flat faceted representations of the object being predicted. This paper compares inverse synthetic aperture radar (ISAR) images generated from XPATCH data to those generated from measured data. Two simple multi-bounce geometries are used in this comparison.<<ETX>>
