Gain calibration of phased array feeds


Phased array feeds can greatly increase the field of view of interferometric radio telescope arrays. High dynamic range imaging with these arrays requires compensation for drifts in the many receiver-chain gains. A calibration system using surface radiators is proposed for the Australian Square Kilometre Array Path Finder. Design considerations and a… (More)
