基于测量数据库的多模馈电网络分析方法

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,直接分析其结构非常困难。本文将互联网络子结构分析理论应用于馈电网络的分析中,通过将复杂的通信系统划分为子结构级联的形式,然后通过设计和建立不同子结构的有效精确的参数测量数据库,并运用测量数据库的变换、级联技术实现对复杂馈电网络特性的有效表达、分析,进而反过来指导馈电网络的优化过程。

A Method of Analysing in Multimode feed Network based on measurement database

Feed network is an important part of shortwave multimode multifeed antenna system.The design of feed network is a pivotal technique in the process of projecting antenna system.To analyze its characteristics directly is very difficult.In this paper,the Substructure Analyzing Method of Interconnectnet is applied to analysing it,the theory plot the complex communication system out the cascading of a set of simple substructures;through designing and setting up the effective and accurate parameter measurement database of different substructure,with the direct use of the measurement database data and the use of some technologies such as transform,cascade,the net characteristic will be performed and analyzed effectively;so that may direct the optimize process of feed network
