Optimal Dithering Configuration Mitigating Rayleigh-Backscattering-Induced Distortion in Radioastronomic Optical Fiber Systems
Jacopo Nanni, Andrea Giovannini, Enrico Lenzi +5
In the context of Radioastronomic applications where the Analog Radio-over-Fiber technology is used for the antenna downlink, detrimental nonlinearity effects arise because of the…
The Engineering Development Array 2: design, performance and lessons from an SKA-Low prototype station
Randall Wayth, Marcin Sokolowski, Jess Broderick +21
We present the Engineering Development Array 2, which is one of two instruments built as a second generation prototype station for the future Square Kilometre Array Low Frequency A…
The Aperture Array Verification System 1: System overview and early commissioning results
P. Benthem, R. Wayth, E. de Lera Acedo +51
The design and development process for the Square Kilometre Array (SKA) radio telescope, the Low Frequency Aperture Array component, was progressed during the SKA pre-construction…
Characterization of the SKA1-Low prototype station Aperture Array Verification System 2
Giulia Macario, Giuseppe Pupillo, Gianni Bernardi +16
The low frequency component of the Square Kilometre Array (SKA1-Low) will be an aperture phased array located at the Murchison Radio-astronomy Observatory (MRO) site in Western Aus…
A Southern-Hemisphere all-sky radio transient monitor for SKA-Low prototype stations
M. Sokolowski, R. B. Wayth, N. D. R. Bhat +20
We present the first southern-hemisphere all-sky imager and radio-transient monitoring system implemented on two prototype stations of the low-frequency component of the Square Kil…
Controlling Rayleigh-Backscattering-Induced Distortion in Radio over Fiber Systems for Radioastronomic Applications
Jacopo Nanni, Andrea Giovannini, Muhammad Usman Hadi +6
Radio over Fiber (RoF) Systems exploiting a direct modulation of the laser source are presently utilized within important Radioastronomic scenarios. Due to the particular operating…
Signal Processing Firmware for the Low Frequency Aperture Array
Gianni Comoretto, Riccardo Chiello, Matt Roberts +22
The signal processing firmware that has been developed for the Low Frequency Aperture Array component of the Square Kilometre Array is described. The firmware is implemented on a d…
