馈电网络是短波多模多馈天线系统的重要组成部分,因此,馈电网络的设计是多模多馈天线系统设计的关键技术。互联网络子结构分析理论以网络参数数据化后形成的矩阵数据库为基础,利用矩阵数据库方法表示非均匀性子结构网络单元的网络参数。文中基于互联网络子结构分析方法,利用数据插值算法对馈电网络的传输线变压器S参数测量数据库进行了无缝化处理。插值结果表明,该算法能在满足一定的插值精度和插值效率的条件下对数据进行有效的插值处理。
The feed network is an important part of the short-wave multi-mode multi-feed antenna system. Therefore, the design of the feed network is the key technology of multi-mode multi-feed antenna system design. Based on the matrix database formed by the network parameterization, the Internet sub-structure analysis theory uses the matrix database method to represent the network parameters of the heterogeneous sub-structure network elements. In this paper, based on the analysis of sub-structure of the Internet, the data interpolation algorithm is used to seamlessly process the S-parameter measurement database of the transmission line transformer in the feed network. The interpolation results show that this algorithm can effectively interpolate the data under the condition of satisfying certain interpolation precision and interpolation efficiency.
