摘 要:尽管计算机仿真功能强大,但物理模型实验在天线系统设计中的作用仍不容忽视。由麦克斯韦方程出发,对天线系统建模时缩比模型参数需要满足的条件进行推导,进而得出天线系统与缩比模型之间相关物理量的转换关系。以美军罗罗里和卡特勒甚长波天线为例,利用所推公式对相应物理缩比模型的对应参数进行计算,总结建立缩比模型及实验的大致流程,为今后天线系统缩比模型的建立起指导作用。Though the function of computer simulation is powerful,the role of physical model experiment in the antenna system design allows of no ignorance.Based on the Maxwell equations,conditions to be fulfilled when the antenna system reduced-scale model is estab-lished are derived,and thus the related physical quantities conversion relation between the antenna system and the reduced-scale model are obtained.Taking the American Laulaulei and Culter VLF antenna as example,the derived formula is used to calculate the corre-sponding parameters of the corresponding model, and the process for establishing the reduced-scale model and making experiment is summarized.The researchcan provide guidance for future establishment of antenna system reduced-scale model.
