Phased-array 64-element 20-MHz receiver for data capture and real-time beamforming

The Brigham Young University (BYU) Radio Astronomy group, in collaboration with Cornell University, the University of Massachusetts, and the National Radio Astronomy Observatory (NRAO), have developed a phased-array feed receiver with sufficient bandwidth and elements for basic scientific use. This paper summarizes the capabilities of this 20-MHz, 64-element FPGA-based system.
