本文借助对假想基阵的分析,求出任意形状大基阵指向性图和加权函数的对应关系导出了加权函数的近似表达式。通过圆弧阵和线列阵两个数值例子,说明运用合成方法能实现预定的设计要求。设计波束宽度存在最佳值。以均匀间距线列阵作了实验验证,波束宽度理论值和测量值一致性较好。 In this paper, with the help of the analysis of hypothetical matrices, the correspondence between the directivity graph of arbitrary shape and the weighting function is obtained and the approximate expression of the weighting function is derived. By arc and linear array two numerical examples, the use of synthetic methods to achieve the desired design requirements. There is an optimal design beamwidth. Experiments were carried out on the linear array with uniform spacing. The theoretical values ​​and the measured values ​​of the beam width were consistent.
