Data Interpolation Application in the Design of Multimode Feed Network at Low Frequency

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。

Multimode feed network is an important part of short-wave multimode multi-feed antenna system. The design of feed network is a key technique in the design of antenna system. The substructure theory of interconnected network is based on the substructure matrix database formed by converting the network parameters into data. In order to satisfy the requirement of seamless processing, the rudimentary approach of interpolation algorithm is adopted and analyzed in this paper. The interpolation result indicates that ＂S＂ parameter measurement database of the transmission-line transformer can achieve effective data interpolation disposal by using the algorithm with proper interpolation precision.
