PARTIAL SURVEY OF CODES FOR HIGH FREQUENCY SCATTERING FROM FACET MODELS OF RADAR TARGETS

Abstract

In this work, four high-frequency electromagnetic scattering codes are surveyed with regard to their capabilities and limitations for the calculation of the radar cross section (RCS) of facet models of targets. The codes discussed are MISCAT, NRCPTD, McPTD, and Xpatch. All of these codes utilize the physical theory of diffraction (PTD) to approximate the field scattered from the target. A short discussion of the modeling features of each code is given and some sample numerical results are generated. It is concluded that, of the models considered here, Xpatch possesses the most comprehensive modeling features available, with no loss in accuracy over the other codes.
