摘要
提出了在非等比缩比条件下,即波长与目标尺寸缩比因子不一致的条件下,采用可见光波对微波电磁系统进行大尺度缩比仿真的新思想。从物理相似性和技术可行性上分析了利用可见光波缩比模拟微波电磁系统中电磁散射效应的可行性,对微波光波非等比测量的分析方法进行了研究,讨论了在非等比缩比条件下,目标雷达散射截面积测量和电磁环境多径效应模拟测量两种典型应用中光频模型系统与微波原型系统的相似关系和相似条件。研究成果是对缩比测量研究的有益探索,为在实验室等较小场地实现大型电磁系统缩比仿真测量实验提供了新思路。
Light wave model measurement microwave system at big scale factor on inequality electrical length conditions was proposed. The analysis idea of such model measurement was put forward. The feasibility of simulating electromagnetic scattering at microwave band using optic wave was discussed from the angle of physical similitude and technological feasibility. Then according to this idea, the similitude relationship and conditions in the application such as RCS measurement and multipath effect measurement were analyzed in detail on inequality electrical length conditions model measurement. The research result offers a new research approach in the field of large scale electromagnetic system simulation.
