A method for fast optimization of full-space beam sidelobe of planar array antenna

A method for fast optimization of full-space beam sidelobe of planar array antenna features that main lobe and sidelobe area of whole space beam of antenna are quickly searched by utilizing antenna beam characteristic to realize fast optimization of sidelobe of whole space beam of antenna to overcome the disadvantage of low efficiency of a planar array antenna. The method can remarkably improve the sidelobe optimization efficiency, has the advantages of simple realization and good universality, and does not depend on the array element type of the planar array antenna element. 本发明公布了种平面阵列天线全空间波束副瓣快速优化方法，针对平面阵列天线在全空间波束副瓣优化时效率低下的缺点，利用天线波束特点快速寻找天线全空间波束主瓣与副瓣区域，实现了天线全空间波束副瓣快速优化的目的。本发明能够显著提高副瓣优化效率，而且实现简单、通用性好，不依赖平面阵列天线单元的阵元类型。
