摘　　要：均衡器、多模多馈天线是具有复杂结构的微波器件,由于其测量数据库总是由离散的有限点集组成,因而对其子结构测量数据库采用插值法进行无缝化处理就成为这些微波器件优化设计的关键技术之一。针对这些微波器件的测量数据库,提出了一种工程上实用的多维插值算法,并介绍了该算法的主要思想。利用C++Bu ilder编程软件和MATLAB拟合软件,给出了均衡器、多模多馈天线的插值实例,并利用Origin图形软件对其插值特性进行了分析和改进。计算和分析结果表明,该算法能在较高的插值精度条件下对数据进行有效的插值处理。且该算法在微波器件的工程设计中具有一定的推广应用价值。Equalizer and muhimode multi-feed antenna are the microwave apparatus of complex microwave structure. Using the interpolation algorithm to dispose the measurement database is the key in the design of microwave apparatus..A multivariable interpolation algorithm which aims at the measurement database of complex microwave structrues is presented here. The mainly thought of this algorithm is introduced in this paper. Using the C ＋ ＋ Builder software and Matlab fit software, the paper also presents the interpolation examples of microwave equalizer and muhimode multi-feed antenna. The improvement of interpolation algorithm is presented here by using the Origin software. The results of calculation indicate that the two kinds of measurement database can achieve effective data interpolation disposal by using the algorithm with proper interpolation precision. The algorithm has great practical value in microwave engineering designs
