Phased Arrays - Brian Jeffs (SETI Talks)

SETI Talks Archive: http://seti.org/talks

Several groups are now working to develop hardware and algorithms for phased array feeds (PAFs) on mid to large sized dish telescopes. The potential benefits are significant, including wide field of view observations using a grid of simultaneously steered beams, single dish rapid imaging, fast survey times, and new methods for interference mitigation. However, there are some challenging problems to address, such as strong mutual coupling between array elements, increased system noise temperatures, hardware complexity at the telescope and beamformer back ends, practical calibration and beamformer design, and broadband operation. Dr. Brian Jeffs will discuss these issues and progress made to date by the Brigham Young University - NRAO Green Bank team.
