摘要: |
分析了干涉仪阵天线的主旁瓣特性,提出了一种利用天线转动来切除旁瓣的新方法,从而在不增加单独全向天线条件下,有效地解决了天线阵旁瓣切除的问题.实验室测试结果证明了这种方法的有效性. |

A New Side-lobe Suppression Method Based on Antenna Rotation |
|
() |
Abstract: |
This paper proposes a new side - lobe suppression method of antenna without auxiliary omni - antenna. The new method makes full use of the difference between antenna main - lobe and antenna side - lobe to effectively suppress the influence of side - lode and identify the fight direction of arrival of target when antenna is rotating. Test results in laboratory verify the effectiveness of the new method. |
