本报告的目的是描述和比较 ABF(自适应波束形成)中采用的各种算法。本文主要是为需要了解自适应波束形成的人介绍基本知识。讨论了矩阵变换、梯度搜索和互相关矩阵的本征值分解等各方面的技术。波束形成导论给出矩阵表示式,并对性能判据作了阐述和比较。虽然各种算法的详细推导已被省略,但给出了方框图、假设、限制条件、结论和所有有用的资料. The purpose of this report is to describe and compare the various algorithms used in ABF (Adaptive Beamforming). This article is mainly for people who need to understand adaptive beamforming to introduce the basics. The techniques of matrix transformation, gradient search and eigenvalue decomposition of cross-correlation matrix are discussed. The introduction of beamforming gives the matrix representation and expounds and compares performance criteria. Although the detailed derivation of various algorithms has been omitted, a block diagram, assumptions, constraints, conclusions and all useful information are given.
