<p indent="0mm">A phased array receiver is an array reception technology that places a small phased array antenna at the focal plane of a radio telescope. By controlling the amplitude and phase of the output signals from each antenna element through a backend beamforming network, the formed beams overlap to achieve continuous field-of-view coverage. Similar to traditional receivers, the core performance metric of a phased array receiver is its equivalent noise temperature. Based on the design of
