Modified Woodward synthesis method and application to design the feed of large aperture antennas

摘要: 在分析传统的Woodward综合方法及其改进方法的基础上,引入最小二乘及伪逆,得到一种新的方向图综合方法;并将新方法与阵列波束形成技术结合,用于设计大型口面天线/FAST(Five-hundred meter Aperture Spherical Telescope)的初级方向图.在本文提出的方法中,抽样点数可以与阵列单元数相等和不等,对综合区域没有限制,所以综合的赋形波束更加灵活,适应场合更广泛.Abstract: A new method of antenna directional pattern synthesis using least-squares or pseudoinverses is presented here ,which is based on the analysis of traditional Woodward-Lawson synthesis method and other modified methods. This new method combined with array beamforming technology is used to design the elementary directional pattern of large aperture antenna/FAST(five-hundred meter aperture spherical telescope). The number of samples can be either equal to or larger than the dimension of antenna arrays in this presented method.And there is no constraints in the synthesis areas.So the synthesized beamforming is much more flexible, and has much wider application situations.
