RCS Predictions From a Method of Moments and a Finite-Element Code for Several Targets

Abstract

This report presents results of radar cross section (RCS) calculations for several interesting targets using a method-of-moments code and a finite-element code. A physical optics code does not handle the mechanisms that contribute to the RCS for the targets and was not an option. These two codes calculate the RCS of an object in very different ways, but the results from the two codes agree very well in regions where the RCS is large enough to matter. The predictions of the codes were also in good agreement with experimental data for one of the targets.
