| 摘 要： | GRECO(Graphical Electromagnetic Computing)技术是目前分析高频区复杂目标雷达散射截面(RCS)最有效方法之一.对低散射截面目标而言,行波效应往往贡献显著,在行波效应较强的某些区域,行波值甚至超过面元与棱边贡献,本文通过GRECO与行波混合法求解低散射目标后向RCS.利用低散射支架为实例,给出与实验结果符合良好的RCS曲线,具有工程实用价值.

| Abstract: | GERCO(Graphical Electromagnetic Computing) is recognized as one of the most valuable methods of RCS computation for the high frequency region. To the low RCS target, the effect of traveling wave is remarkable and larger than that of facets and wedges in some cases. This paper shows satisfying results by using the hybrid method of GRECO and traveling wave theory. It gives the RCS curves of a low scattering prop, which are satisfying measured results. The results can have practical engineering worth. |
