摘　　要：阵列天线波束展宽技术越来越受到关注。针对发射阵列天线的技术特点,采用基于傅里叶变换的波束综合方法进行唯相加权波束优化展宽,以32单元阵列为例进行不同波束展宽倍数仿真,并就波束展宽性能进行分析,仿真结果表明仅通过相位加权就可以实现很大的波束展宽范围。The beam broadening technology is receiving increasing attention.In this paper,a beam broadened method based on inverse discrete Fourier transform is introduced,and the different amount of beam broadening of 32 element linear array is discussed,it's shown that the beam broadening factor can be achieved in wide range based phase-only adjustments.
