提出了一种合成低旁瓣波束图的新方法，该方法可以相对独立地调节波束宽度和旁瓣电平。与现有的任意波束图合成方法（如[8]-[10]）不同，该方法基于对dolphi - chebyshev[1]设计的改进，只需要优化几个参数，而不考虑阵列大小。由于复杂度低得多，该方法可用于无线通信应用，需要快速和廉价的低旁瓣阵列[5]，[6]，[12]的自适应算法。该方法适用于均匀圆形阵列自适应扇区天线的设计，以及均匀线性阵列准导向不变波束方向图的设计。
A new method for the synthesis of low sidelobe beampatterns is presented, which enables b.eamwidth and sidelobe level to be adjusted with relative independence. Unlike existing methods for the synthesis of arbitrary beampatterns, e.g., [8]-[10], the proposed method is based on a modification of the Dolph-Chebyshev [1] design and requires only a few parameters to be optimized, regardless of the array size. Due to its much lower complexity the method is implementable in wireless communications applications requiring fast and cheap, adaptive algorithms for low sidelobe arrays [5], [6], [12]. The method is applicable, for instance, to the design of adaptive sector-like antennas with uniform circular arrays (UCAs), and to the design of quasi-steering-invariant beampatterns with uniform linear arrays (ULAs).
