| 摘 要： | 从再入体典型口径天线在无限大平面上的辐射场出发,采用几何绕射法(GTD),计算分析了不同口径分布的再入体缝隙天线赤道面和子午面辐射场随再入体模型纵向尺寸的变化,实验验证了其计算分析结果,从理论分析和实验得出了可忽略截短效应的再入体模型纵向尺寸。

| Abstract: | In this paper, the pattern variation of aperture antenna with different polarization versus the truncation size of reentry body(RB) mockup is analyzed with geometrical diffraction techniques(GDT). On the basis of analysis, truncation effect of RB mockup on antenna pattern is evaluated in elaboration with experiment, thus the minimum mockup sizes corresponding to different aperture polarization on which the antenna pattern measurement error due to truncation is neglectible is obtained |
