摘要

为了满足毫米波通信减少对同频段卫星通信干扰的需要，本文提出了一种基于迭代傅立叶变换(IFT)算法的合成方法，在特定角度范围内获得低平均旁瓣电平(ASLL)的方向图。并在程序中加入了波束宽度控制(BWC)方法来控制方向波束宽度。优化结果表明，通过优化单元激励的相位和幅值，该方法可以在要求的角度范围内获得-43.31 dB的ASLLS，并且基本不会增加288元平面阵列的波束宽度。

Efficient Suppression of Average Sidelobe Level for Millimeter-Wave Antenna Array by Using Iterative FFT

In order to meet the needs of millimeter(mm)-wave communication for reducing interference to satellite communications within the same frequency band, this paper presents a new synthesis method based on the iterative Fourier transform (IFT) algorithm to obtain a pattern with low average sidelobe level (ASLL) within a specific angle range. And the beamwidth control (BWC) method is also added in the procedure to control the pattern beamwidth. The optimization results show that the proposed method can obtain an ASLLS of -43.31 dB within the required angular range and basically no increase in beamwidth for the 288-element planar array by optimizing the phase and amplitude of the element excitations.
