摘　　要：多模馈电网络是短波多模多馈天线系统的关键部件,实现其高效、精确的优化设计,将为整个多模多馈天线系统的优化设计奠定良好的基础。本文基于互联网络子结构分析方法,利用距离倒数权值插值方法对馈电网络的测量数据库进行了无缝化处理。研究结果表明,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,它在多模馈电网络中的有效应用将为整个多模多馈天线系统的优化提供有利的支持。Muhimode feed network is the key of the shortwave muhimode multi-feed antenna system. Its effective and precision optimizing design will provide a base for the entire muhimode multi-feed antenna system＇ s optimizing design. In order to satisfy the requirement of seamless datum, the interpolation algorithm based on the distance＇s reciprocal is adopted and analyzed in this paper.
