| 摘 要： | 对引信半实物射频仿真中的近场效应进行了研究。建立了引信射频仿真中阵列单元天线在引信天线上产生球面波的相对幅值与相位,以及锥削的解析式。推导了球面波条件下引信射频仿真阵面曲率半径的计算公式。研究认为：若参试引信天线参数不满足球面波条件的计算公式时,须对近场效应的锥削进行修正。

| Abstract: | The short-range effect in fuze radio frequency simulation was studied in this paper. The expressions of the relative amplitude, phase, and loss relative to center of spherical wave produced by array antenna units on the fuze antenna in fuze radio frequency simulation were established. The formulas of loss relative to center used fuze simulation were derived. The study showed that the loss relative to center of spherical wave should be amended if the formulas were not satisfied for the parameters of the fuze antenna in the simulation. |
