【摘要】 依球面波展开法等绕射理论,对偏焦轴天线的副面散射场、次级方向图和效率作了分析。理论计算和实验结果的良好吻合,表明文中给出的计算公式对于工程应用是有效的。更多还原

【Abstract】 The scattered field from the subreflector, the secondary radiation patterns and the efficiency of (he shifted focal axis antenna are analysed by means of spherical wave expansions etc. diffraction theories. The calculated results are in good agreement with the experimental one, and show that these formulas are effective for the engineering design.更多还原
