摘　　要：利用建模软件UG5.0对某装甲进行建模,分别应用基于求解微分方程的时域有限差分法FDTD和基于求解积分方程的FEKO5.3软件对模型进行仿真计算与分析,得出该装甲在锥扫式毫米波近程雷达照射方向下各种姿态的雷达散射截面积和方向图。结果表明,此两类算法可以实现较准确的电磁散射建模计算,不仅为毫米波近程雷达半实物仿真测试系统提供了大量的装甲目标特性数据库,而且可以节省人力物力,加快项目的研究进度。By simulating and analyzing an armor modeled by UG5.0 with the algorithm FDTD based on differential equation and FEK05.3 based on integral equation, the RCS and pattern of the armor various pose was obtained in the condition of MMW conical-scan radar irradiation orientation. Results indicate that the electromagnetic scattering modeling is exact, at the same time the two kinds of algorithms not only provide plenty of armor character databases for MMW short range radar HWIL simulation test system, but economize on manpower and material resources and speed up project schedule research as well.
