摘要
运用迭代物理光学法(IPO)计算了角反射器和腔体的电磁散射作用,分析了网格划分粗细和迭代次数对RCS计算的影响,并与不同的文献结果和测量结果进行比较,两者有较好的一致性,说明了本文计算采用的公式和程序的可靠性。在此基础上,计算了角反射器和腔体的近场RCS值。
<Abstrcat>Employing the iterative physical optics method, the electromagnetic scattering of the corner reflector and cavity are calculated. Analyzes the influence to the RCS calculated by the partition of grid thickness and the times of iterative. The RCS results are in good consistent with reference and measured data, demonstrating the credibility of formula and codes applied by the article. On the basic, calculates the near field RCS of corner reflector and cavity.
