为了减小线形天线阵辐射图形中的旁瓣,本文前一作者提出了与辐射图形中零点相对应的复量多项式的根在复数面中单位圆上的一个分布函数。这个分布函数是ψk=(2βl)/(1-n){1+ξk(1-(lnε)/(ln(n-2)))},它包含了谢昆诺夫的均匀分布(ξ=1);因此,谢昆诺夫的分布可以看成是我们的分布的一个特例。计算结果证明,应用我们的分布函数,对于不均匀线形天线阵的辐射图形将有较好的控制,尤其对于减小主瓣附近的旁瓣有利。这样作会使远离主瓣的旁瓣变大一些,但后一清况可以用本文前一作者所提出的移动最末一个零点的位置加以改善。The first writer suggests a distribution function for the roots of the complex polynomial corresponding to the nulls of the radiation pattern of a nonuniform array on the unit circle in a complex plane for the purpose of suppression of the side-lobes near the main beam of radiation.This distribution function includes the uniform distribution suggested by Schelkunoff as a special case. Computed results show that by means of this distribution function, a better control of the radiation pattern of a nonuniform linear array can be achieved, especially for the purpose of suppression of the first few side-lobes near the main beam which is important in certain applications at the expense of increasing relatively far off side-lobes. However, the most far off side-lobe can be suitablly reduced by the appropriate shifting of the last null.
