چکیده
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 an hierarchical, frequency-domain beamforming architecture for synthesising a sky beam from the wideband antenna feeds of digital aperture arrays.

A Digital Broadband Beamforming Architecture for 2-PAD
Abstract. We describe an hierarchical, frequency-domain beamforming architecture for synthesising a sky beam from the wideband antenna feeds of digital aperture arrays. The development of densely-packed, all-digital aperture arrays is an important area of research required for the Square Kilometre Array (SKA) radio telescope. The design of real-time signal processing systems for digital apertur...
متن کاملTDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire
Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...
متن کاملSystem Noise Analysis of an Ultra Wide Band Aperture Array Element for Low Frequency Radio Astronomy
One of the biggest challenges in radio astronomy for the 21st century is the SKA telescope, the newest radio telescope in the world to be built as a Square Kilometre Array of antennas distributed in hundreds of stations to form an interferometric image of the sky. Below 1 GHz, these stations will be composed of thousands of inexpensive elements in a dense or sparse configuration delivering data...
متن کاملAperture Arrays for the SKA : Dense or Sparse ?
We briefly consider some design aspects of aperture arrays for use in radio astronomy, particularly contrasting the performance of dense and sparse aperture arrays. Recent insights have emerged in the final design phase of LOFAR which suggest that sparse aperture arrays have the best prospects for cost-effective performance at radio frequencies below about 500 MHz; exceeding those of both dense...
متن کاملFIR-filter based RF-beamforming network for wideband and ultra wideband antenna arrays
In this paper, a wideband electronic beamforming concept applicable for UWB short pulse systems is derived and experimentally demonstrated. In particular, a Finite Impulse Response (FIR)-filter based beamforming network is configured such that an antenna array yields a desired radiation pattern within a predefined frequency range. An experimental verification of a wideband transmission system i...
