RCS prediction comparison between physical optics and moment method techniques

The analysis of complex scattering objects can be accomplished using various numerical methods. Two complementary techniques that have found great success in many classes of electromagnetic applications are the moment method (MM) and the physical optics techniques. This paper will present results of RCS predictions using Riverside Research Institute modified moment method code ´IBC3D´ and Georgia Tech Research Institute developed physical optics code ´GTS´. Some of the predicted results will also be compared to the measured results.
