Encircled power study of focal plane field for estimating focal plane array size

TL;DR: In this paper, the relationship between the size of a focal plane array and achievable scan angle is studied in order to find a starting point for designing such systems, and the authors found that the focal plane fields are largely independent of the dish size when the scan angle was expressed in beamwidths.
Proceedings ArticleDOI

Phased array feed testing for astronomy with ASKAP

TL;DR: In this article, a 5 × 4 port × 2 polarisation connected-chequerboard array was tested at the prime focus of a 12 m diameter parabolic reflector for the Australian Square Kilometre Array Pathfinder (ASKAP).
Journal ArticleDOI

The Australian Square Kilometre Array Pathfinder: System Architecture and Specifications of the Boolardy Engineering Test Array

Aidan Hotan, +99 more
TL;DR: The Boolardy engineering test array is a prototype of the Australian square kilometre array pathfinder telescope, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously, allowing several square degrees to be imaged in a single pointed observation.
Proceedings ArticleDOI

Design and laboratory testing of the five hundred meter aperture spherical telescope (FAST) 19 beam L-band receiver

TL;DR: In this paper, a multibeam receiver for the FAST radiotelescope was described, which provides 19 dual polarised beams over a band of 1050-1450 MHz with an expected receiver noise temperature under 7 K and aperture efficiency of greater than 62%.
Proceedings ArticleDOI

Measuring radiotelescope phased array feed noise and sensitivity

TL;DR: In this article, the authors focus on measuring the equivalent noise temperature and the sensitivity of these feeds and outline the differences between characterizing phased array feeds compared with traditional single horn feeds and provide results from their experience in developing phased array feed for the Australian Square Kilometre Array Pathfinder.
