摘 要: 针对等间距圆形阵的波束宽度、副瓣电平等波束性能指标一般难于由阵元参数进行定量分析,从而给工程设计带来诸多不便这一问题,在分析等间距圆形阵波束形成原理的基础上,通过计算机仿真的方法进行数值模拟和数据分析,导出了等间距圆形阵的波束宽度、副瓣电平等与阵元数N、阵半径R等阵列参数以及信号波长λ之间的定量关系。 Performance indicators such as Beamwidth and SLL for uniform circular array(abbr.ULA) are difficult to be derived from the array parameters,and cause some inconvenience to the engineering design.To solve this problem,the principles of the ULA are analyzed,and then the quantitative relationships between Beamwidth as well as SLL and the array parameters such as the number of array elements N,the array radius R and the signal wavelength λ by numerical simulation and data analysis are derived.
