|MK3 Phased Array Feed|
|by Alex Dunning (CASS)|
Today's image shows CSIRO's MK3 40-port phased array feed -- with its characteristic "rockets" -- undergoing testing in the Parkes aperture array test facility.
The test facility uses an ASKAP digital backend to measure the response of the new-design phased array feed when illuminating a room temperature load
and when illuminating the sky.
