柱形弹体引信天线布局与作用盲点分析

在单天线横截面方向图计算公式的基础上，计算了圆柱体导弹引信双天线、三天线和四天线布局的方向图。讨论了不同布局下引信载频、弹体直径及天线布局与作用盲点的关系。双天线布局的实际测试表明，测试值与计算结果较为吻合，所用的计算方法正确，可为引信天线布局与引信工作频率确定提供设计依据。

Analysis of the Relation between Blind-Spot and Fuse-Antenna's Position of Cylindric Missile

The directional figures of double-antenna, three-antenna and four-antenna in cylindric missile fuse were computed on the basis of figure of one-antenna at the cross section in this paper. The relationship among the fuse frequency, the diameter of column body and the positions of the fuse antenna in different fuse layout was discussed. The test result of double-antenna showed that the figure measured was similar to the one computed. The algorithm used was right, which could be applied in the design of antenna layout and fuse frequency.
