Simulation and optimization of novel movable TEM horn radiating-wave simulator

  • 摘要: 为改善基于TEM喇叭的辐射波模拟器的低频辐射特性从而展宽其辐射近场半高宽,首次提出了在指数型TEM喇叭上/下两个极板的端口加上2个金属直板、并通过倾斜金属板和并联电阻相连的新型可移动模拟器的设计方案。基于FDTD方法模拟分析了该新型模拟器的特性参数对其近场辐射性能的影响,并给出了优化后的模拟器及其阵列的辐射特性。计算结果表明:尺寸为6 m×6 m×6.24 m的优化后的新型模拟器在距离口面3 m的中心位置的辐射近场脉宽能达到18.95 ns,而达到相同低频辐射性能的常规模拟器尺寸为9 m×12 m×6.8 m。且与常规模拟器相比,优化后的模拟器的场峰值更大。与前人的研究相比,优化后的模拟器场在保持高峰值的同时,时域波形后延震荡的幅度与主峰的比值明显减小。优化后的模拟器2×2阵列模型的测试平面中心点场峰值最大,且在测试平面上满足6 dB均匀性要求的有效测试区最大;有效测试区在横向上范围最大的是2×2阵列模型,其次是2×1阵列模型;在纵向上范围最大的是2×2阵列模型及1×2阵列模型。
