作为照射器的馈源 ,反射面天线和透镜天线主要要求两主面相心应尽量靠近 ,两主面波办应尽量相等 ,波导尺寸应与塔形喇叭匹配 ,由此建立电性与照射器的几何结构参数的优化数学模型。通过寻优 ,得到了较为满意的优化结果 ,为照射器的二次开发设计提供了可靠的依据 As the illuminator’s source, the reflecting surface antenna and the lens antenna mainly require that the two main surfaces should be as close as possible, the two main surfaces should be as equal as possible and the waveguide size should be matched with the tower-shaped speaker to establish the electrical and illuminator Optimization Mathematical Model of Geometric Structure Parameters. Through optimization, we get a more satisfactory optimization results, which provide a reliable basis for the secondary development and design of illuminator
