射电天文密集孔径阵列宽带四元全数字波束形成系统

A Wideband, Four-Element, All-Digital Beamforming System for Dense Aperture Arrays in Radio Astronomy

Richard P. Armstrong, Kristian Zarb Adami, Mike E. Jones

摘要:

密集排列的全数字孔径阵列是平方公里阵列(SKA)射电望远镜所需技术开发的一个关键领域。数字孔径阵列的实时信号处理系统的设计是目前世界范围内探路者项目的核心挑战。我们描述了这样的工作的中期结果;一个分层的,频域波束形成架构,用于合成从数字孔径阵列的宽带天线馈源的天空波束。

英文摘要:

Densely-packed, all-digital aperture arrays form a key area of technology development required for the Square Kilometre Array (SKA) radio telescope. The design of real-time signal processing systems for digital aperture arrays is currently a central challenge in pathfinder projects worldwide. We describe interim results of such work; an heirarchical, frequency-domain beamforming architecture for synthesising a sky beam from the wideband antenna feeds of digital aperture arrays.
