摘　　要：将空间映射算法推广到共形天线阵的优化设计之中,并首次使用该方法对天线的方向图特性进行优化。粗糙模型采用腔模理论结合圆形天线阵理论进行分析,精细模型采用全波电磁仿真软件HFSS整体建模仿真进行分析。计算结果表明,该方法对天线阵方向图特性的优化设计是可行的,并且只需对精细模型计算很少的次数就可以实现优化目标,具有很高的设计效率。Space Mapping Algorithm was extended to optimize conformal antenna array,and was used to optimize the radiation pattern for the first time.At first,the coarse model was analyzed by the cavity-model theory combined with the circular array theory,then the fine model was analyzed by the full-wave electric magnetic simulation software HFSS.Results show that only several simulations towards the fine model was needed to achieved the optimization goal by this method,thus demonstrated the feasibility and the great efficiency in the optimization of the antenna design.
