Abstract

A Focal L-band Array Feed for the Green Bank Telescope (FLAG) has been in development for the last five years. The system comprises a 19 element, dual polarized hexagonal antenna array, cryogenic front end amplifiers, direct RF to digital over fiber conversion, and broadband, real time digital signal processing. Phased array feeds enable continuous wide field, radio camera imaging on a large reflector. FLAG was mounted in summer 2017 on the GBT in West Virginia, USA as part of commissioning tests. We report on measured receiver figures of merit and experimental results, and comparisons to simulated performance. The measured results indicate that the FLAG instrument achieves unprecedented field of view, sensitivity, and survey efficiency.
