摘要

本文力求建立一种便于主波束角分辨率分析的道夫-切比雪夫线性天线阵首零波束宽度的设计表达式。通过观察FNBW随旁瓣比的变化，推导出了FNBW的计算公式。本文还考虑了不同阵列构型下FNBW随单元间距的变化。用该公式计算的FNBW值与阵列因子图计算的FNBW值进行了比较，证明了其有效性。

Design expression for first null beam width of broadside Dolph Chebyshev antenna array

This paper strives to postulate a design expression for the first null beam width (FNBW) of Dolph Chebyshev linear antenna array which facilitates the angular resolution analysis of main beam. The formula for FNBW has been deduced by observing variation of FNBW with required side lobe ratio. Variation of FNBW with inter-element spacing for different array configurations has also been taken in to consideration. FNBW value obtained using the proposed formula has been compared with that of FNBW value obtained from the array factor plot proving its effectiveness.
