Measuring radiotelescope phased array feed noise and sensitivity

Various challenges have arisen in the measurement of phased array feeds for radiotelescopes. We focus here on measuring the equivalent noise temperature and the sensitivity of these feeds. We outline the differences between characterizing phased array feeds compared with traditional single horn feed...
