Verification of the Radar Cross Section Codes
|
|
In 1999 and 2006 the current
computational electromagnetic codes were evaluated in order to determine
their accuracy and regions of validity.
The codes that were evaluated were a Method of Moments (MoM) code, Wire Code (MoM
code specialized for thin wires) Xpatch (both 1999 and 2006 versions), Lucernehammer
(physical Optics code) and Galaxy (MoM code that
is part of the Lucernhammer package. The results
were compared to theoretical solutions (such as Mie Series) and data (such
as the RCS metal cone measurements and results
from the “Radar Cross Section Handbook” by Ruck, Barrick,
Stuart and Krichbaum). All the dimensions are normalized with
respect to wavelength.
