摘要
主要研究了基于子阵的宽带恒定波束形成方法,探讨了子阵带宽、子阵大小和最大波束偏移角三者之间的约束关系,最后给出了在子阵级实现低副瓣宽带波束形成的条件。
This paper primarily studies the method to form the wideband constant beam based on sub-array,and discusses the restriction relationship among the bandwidth of sub-array,sub-array size and the excursion angle of maxium beam,finally gives the condition to realize the wideband beam forming of low side lobe in the grade of sub-array.
