Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope
W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87
We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…
Numerical Results for the System Noise Temperature of an Aperture Array Tile and Comparison with Measurements
M. V. Ivashina, E. E. M. Woestenburg, L. Bakker +1
The purpose of this report is to document the noise performance of a complex beamforming array antenna system and to characterize the recently developed noise measurement facility…
Experimental Results of the Sensitivity of a Low Noise Aperture Array Tile for the SKA
E. E. M. Woestenburg, L. Bakker, M. V. Ivashina
Aperture arrays have been studied extensively for application in the next generation of large radio telescopes for astronomy, requiring extremely low noise performance. Prototype a…
The latest on Apertif
Tom Oosterloo, Marc Verheijen, Wim van Cappellen
We describe a Phased Array Feed (PAF) system, called Apertif, which will be installed in the Westerbork Synthesis Radio Telescope (WSRT). The aim of Apertif is, at frequencies from…
Apertif - the focal-plane array system for the WSRT
Tom Oosterloo, Marc Verheijen, Wim van Cappellen +3
We describe a focal plane array (FPA) system, called Apertif, that is being developed for the Westerbork Synthesis Radio Telescope (WSRT). The aim of Apertif is to increase the ins…
APERTIF, a focal plane array for the WSRT
M. A. W. Verheijen, T. A. Oosterloo, W. A. van Cappellen +3
In this paper we describe a focal plane array (FPA) prototype, based on Vivaldi elements, developed for the Westerbork Synthesis Radio Telescope (WSRT) to increase its instantaneou…
