A paper presenting the measured sensitivity of CSIRO’s first Mk II phased array feed (PAF) on an ASKAP antenna has been accepted for publication in the 2015 International Conference on Electromagnetics in Advanced Applications (ICEAA).
Results discussed in the paper demonstrate that the Mk II PAF achieves a minimum system-temperature-over-efficiency (Tsys/eta) 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).
