| 摘 要： | 与远场RCS比较,近场散射问题更复杂、更普遍,且有重要意义。近场散射与远场RCS之间的关系是近场散射研究中的前沿课题之一。本文首先引用三天线概念,其次利用天线耦合公式及电磁场的互易定理导出简洁的链条关系式。最后利用线性系统理论中的基本概念对链条关系式作物理意义的解释。链条关系式在目标特性研究、远场和近场散射测量等方面有重要意义。

| Abstract: | Compared with far-field RCS,the near-field scattering is more complex,more general and more important.The relation between the near-field scattering and far-field RCS is one of the state-of-the-art problems in the research on near-field scattering.In this paper,firstly,the concept of three antenna is cited.Sequentially,the compact Chain Relation is educed via the formula of antenna coupling and reciprocal principle.Finally,the physical meaning of the Chain relation is explained with the basic concept of linear system.The Chain Relation is meaningful in the research on target character,the far-field and near-field scattering measurement. |
