分形阵列补集阵的研究

Research on the Complement of Fractal Array

介绍分形Cantor集线阵和Sierpinski集平面阵的基本阵列结构和方向图特性，针对它们方向图高副辫的缺点提出了一种新的阵列结构——分形阵补集阵，这种稀疏阵列的方向图具有更低的副瓣。通过对多种不同分形阵的补集阵的研究，验证了分形补集阵具有更优秀的方向图特性。分形补集阵的提出为低副瓣稀疏阵的设计提供一种新的方法。

Following introduction of Cantor set array and Sierpinski planar array, this paper discusses the disadvantages of their high side-lobes on radiation pattern. Then, a new array structure called Complement of Fractal Array is presented. Its sparse array structure has lower side-lobe. Research on multiple types of Complements of Fractal Array proves that the complementary array has better performance in radiation pattern. Therefore, the complementary array provides a new method for low side-lobe sparse array design.
