Measured Sensitivity of the First Mark II Phased Array Feed on an ASKAP Antenna
arXiv:1509.00544 · doi:10.1109/ICEAA.2015.7297174
Abstract
This paper presents the measured sensitivity of CSIRO's first Mk. II phased array feed (PAF) on an ASKAP antenna. The Mk. II achieves a minimum system-temperature-over-efficiency of 78 K at 1.23 GHz and is 95 K or better from 835 MHz to 1.8 GHz. This PAF was designed for the Australian SKA Pathfinder telescope to demonstrate fast astronomical surveys with a wide field of view for the Square Kilometre Array (SKA).
