| 摘 要： | 应用可视化图形电磁计算(GRECO)技术求解高频区复杂目标面元与棱边后向散射场.对低散射截面的座舱而言,行波效应往往贡献较为显著,在某些空域内行波值甚至超过面元与棱边贡献,通过GRECO与行波混合法分析座舱目标的电磁散射特性,并给出其雷达散射截面(RCS)值.

| Abstract: | Graphical electromagnetic computing (GRECO) is recognized as one of the most valuable methods of RCS computation in high frequency region. For the low RCS cabin, the effect of traveling wave is remarkable and larger than that of facets and wedges in some cases. A practical example of Low RCS target was given to prove the validity of the method by using the hybrid method of GRECO and traveling wave theory. The results were shown to have practical engineering significance. |
