| 摘 要： | 分析仿真了单个平面阿基米德螺旋天线阵元的辐射特性,在此基础上,研究了由该天线为阵元构成的8单元圆形阵列方向图特性,相比于全向阵元构成的8单元圆阵,平面阿基米德螺旋天线阵列可以有效地降低副瓣电平,改善阵列方向图特性。最后讨论了基于MUSIC算法的该阵列测向性能并给出了仿真结果。

| Abstract: | First the radiation characteristic of single planar Archimedean spiral antenna as a basic element of circular array is analyzed and its pattern synthesis is simulated. And then the circular array's pattern synthesis characteristics are introduced in detail. Compared to the 8 units' isotropic array,the directional array's side lobe level is efficiently decreased by using the planar Archimedean spiral antenna as the basic element of the array and the circular array's pattern synthesis characteristics are also... |
