该通信提出了低旁瓣合成的结果，使用仅振幅锥形应用于大型圆形稀疏阵列的打开的元素。低副瓣综合是利用与先前开发的相同的迭代傅里叶变换方法来进行的，以在有缺陷的阵元的情况下恢复原始副瓣性能。所提出的低旁瓣的结果是指高度稀疏的圆形阵列的直径范围从25到133.3波长，并涉及和和差模式。此外，结合低旁瓣扇区调零进行了数值研究。
This communication presents results for the low sidelobe synthesis using amplitude-only tapering applied on the turned ON elements of large circular thinned arrays. The low sidelobe synthesis was carried out with the same iterative Fourier transform method that was developed earlier to restore the original sidelobe performance in case of defective array elements. The presented low sidelobe results refer to highly thinned circular arrays with diameters ranging from 25 to 133.3 wavelengths and involved both sum and difference patterns. In addition, sector nulling in combination with low sidelobes was numerical investigated.
