摘要: 正 (一)傅氏變換迭代法的收斂值和賦形區(qū)外的能量 傅氏變換迭代法是新近提出來的波束賦形方法。其賦形精度和效率是天線設(shè)計者所關(guān)心的問題。本文從迭代法的收斂值和賦形區(qū)以外的能量來表示該方法的賦形精度和效率,現(xiàn)討論如下

Abstract: Fourier transform iterative method for synthesizing a pattern is recently proposed by Feng (1980). The accuracy and effieiency of the method are analyzed, and the result shows that in the shaped region, Fourier transform iterative method will converge to a desired shape, but the energy beyond the shaped region will increase as tha iterative number becomes larger. As example, synthesizing function by the method is given. -
