| 摘要: |
| 为了解决副面遮挡导致小口径卡氏天线(D=293mm)副瓣电平恶化这一难题，本文提出了一种优化赋形方法。采用优化口径场分布，对主、副面形状进行赋形设计。用该法设计了一种八毫米低副瓣卡氏天线(sll1≤-25dB)，实验结果与理论计算十分吻合。 |

| Abstract: |
| Subreflector blockage causes the side lobe level of litlle aperture cassegrain antenna to rise. In order to solve the problem，an optimization-correction method is presented. The method optimizes aperture distribution and corrects the shapes of dual reflector. A 8mm lower sidelobe cassegrain antenna is designed. The experimental result is in agreement with the theory computation. |
