| 摘 要： | 以口径场法为基础对偏置抛物面天线进行建模分析,可方便有效地计算馈源数目任意、馈源放置位置任意的偏置抛物面天线的方向图。通过优化对馈源位置进行调整,使得各波束的性能达到设计的要求,最终实现多波束天线。绕特定的轴旋转馈源阵列,可以实现更大空间的扫描。

| Abstract: | This paper presents the mathematical model of the offset parabolic reflector antenna and analyzes it based on aperture-field method. It is convenient and efficient to calculate the radiation characteristics of the offset parabolic reflector antenna with multi-feed placed arbitrarily. Then,the position of the feed is modified based on the concept of beam optimization to meet the design requirements. Finally,the multi-beam offset parabolic reflector antenna is designed. Revolve the feed array around a certain... |
