摘要
按照某高频地波超视距雷达接收天线阵小型化的要求 ,在 4～ 8MHz频带内 ,采用一种改进型遗传算法对高频宽带集中加载天线及其宽带匹配网络进行了优化设计。同时根据天线工程与实践 ,详细分析了集中加载元件值及加载位置扰动对天线电性能的影响 ,分析表明 。
In order to miniature receiving array antennas of HF surface wave radar, an improved genetic algorithm was applied to optimize the design of HF broad band antenna loaded with lumped components and matching network in 4 MHz-8 MHz. The disturbing effect of loading circuit parameters and their locations on antenna's electrical characteristics was analyzed specifically according to antenna engineering and practice. The analysis illustrates that the loading parameters derived are not quite sensitive to the disturbance after the optimization.
