| 摘 要： | 通过对传统Chebyshev多项式增加修正因子得到一种修正的Chebyshev多项式，并以此为基础提出了一种新的阵列天线方向图综合方法。与传统Chebyshev综合法相比，该方法可以在保持副瓣电平不变的情况下对主瓣进行任意展宽，待求参数少，综合过程简单，有很强的实用性。

| Abstract: | In this paper,a new method for the synthesis of low sidelobe pattern is presented.This new method is obtained from adding a new factor to the traditional Chebyshev polynomial and enables to control the beamwidth and sidelobe level with relative independence.Unlike existing methods,it requires only a few parameters to be got and has much lower complexity. |

| Keywords: | chebyshev polynomial pattern synthesis low sidelobe beamwidth side lobe ratio |
