摘要
由于数字波束形成(DBF)的诸多优点,其已广泛地应用到相控阵上。介绍了DBF的基本原理及划分方法,并分析了不同划分方法的优缺点,最后以一维线阵为例,阐述了子阵划分带来的影响。
Because of a good many advantages of digital beam forming （DBF）,it has been widely used in phased array. This paper introduces the fundamental theory and partition method of DBF, and analyzes the advantages and disadvantages of different partition methods, finally expatiates the influence caused by sub-array partition taking the one-dimensional array as an example.
