弹载天线载体截短对天线辐射特性的影响
内容简介：应用几何绕射理论(GTD)对弹载口径天线载体截短对子午面辐射特性的影响进行了分析计算。截断模型包括弹体尾部圆柱部分、尖端锥体部分以及同时截短尾部圆柱部分和截断尖端锥体部分。计算结果表明，将弹体适当截短对弹载天线子午面内辐射特性影响很小，完全可以在弹载天线的测量中对弹体进行截短处理。
Abstract：The pattern of an antenna in missile was calculated by using GTDmethod. The influence for pattern of the antenna in missile was analyzed when the cylinder of tail, or the cone of head, or both ends of the missile body were truncated according to different lengths appropriately. The results show that the influence for antenna pattern due to truncation of the missile body is very small, thus the truncating disposal for the missile body is entirely possible in the antenna measurements.
